LOKEN, Circuit Judge.

      This is a diversity action removed from state court in December 2015. Iowa
Great Lakes Sanitary District (IGLSD) alleges that an Ultraviolet Wastewater
Disinfectant System (UV System) installed at IGLSD’s Dickinson County
Wastewater Treatment Facility “has consistently failed to function in any working
capacity.” IGLSD asserts a claim against Travelers Casualty and Surety Company
of America (Travelers) under the Performance and Maintenance Bond issued to
guarantee performance by the project’s contractor, and breach of warranty claims
against the UV System vendor, Evoqua Water Technologies, f/k/a Siemens Water
Technologies (Evoqua). IGLSD appeals the District Court’s1 grant of summary
judgment dismissing these claims. Reviewing the grant of summary judgment de
novo, we affirm. Bruce Martin Const., Inc. v. CTB, Inc., 

, 753 (8th Cir.
2013) (standard of review).

                                   I. Background.

       In 2007, IGLSD contracted with McHan Construction, Inc., to complete a
$14,593,000 addition to the Wastewater Treatment Facility, including installation of
a UV System. McHan procured a Performance and Maintenance Bond from
Travelers fully guaranteeing McHan’s “faithful performance of the contract” with
IGLSD. After the contract was in effect, McHan purchased a vertical open channel
UV System from Evoqua for $132,000. The purchase agreement included an express
two-year limited warranty “that the equipment or material . . . is free from defects in
workmanship and materials.” The two-year warranty period would commence on the
date the equipment successfully completed a required sixty-day performance test.

       After McHan defaulted in late 2009, Travelers and IGLSD entered into a “Take
Over Agreement” whereby Travelers agreed “to complete the Project pursuant to the
terms of the Contract,” with its Performance and Maintenance Bond “in full force and
effect.” Start-up problems plagued installation of the UV System, causing further
delays in completing the contract. When the installed UV equipment eventually
completed the sixty-day performance testing, IGLSD’s project engineer, James
Rasmussen, advised the parties on November 8, 2011: “With the latest Performance

       The Honorable Leonard T. Strand, Chief Judge of the United States District
Court for the Northern District of Iowa.

Test on Module No. 2 the UV disinfection equipment is now Substantially Completed
and the project can be finally accepted. The Warranty Period for the equipment will
be considered to be started on November 1, 2011.”

       Substantial Completion did not end the parties’ problems with the UV System,
which IGLSD alleges was often nonoperational. In June 2012, an electrical fire
damaged one of the modules; it was returned to Evoqua’s factory for repairs. In May
2013, IGLSD complained there was soot in the system, it was malfunctioning, and
warranty issues had not been addressed. In a July 2013 letter to Travelers, Engineer
Rasmussen noted the equipment warranty would expire November 1, 2013, expressed
concern that Siemens and Evoqua were not supporting the equipment, summarized
numerous items needing repair, and asked Travelers to “develop a plan to
repair/replace the equipment by the end of the Warranty date.”

       Alerted to these complaints, Evoqua sent a technician to assess the equipment
in September 2013. Based on his report, in April 2014 Evoqua proposed that the two
UV modules undergo a substantial rehab, with IGLSD and Evoqua splitting the
$75,000.00 cost. In a May 12, 2014 letter, Engineer Rasmussen responded that
IGLSD “does not wish to go any further to repair the failed equipment” and requested
that the UV System “be removed from the project and the cost of the initial purchase
of the equipment be refunded.” This lawsuit followed.

       In its summary judgment Order, the district court noted that Chief Magistrate
Judge C.J. Williams had entered an order that “prohibited IGLSD from proffering
expert testimony as a sanction for IGLSD’s failure to comply with the court’s
deadlines.” The district court also ruled that IGLSD had violated Local Rule 56(b)
by failing to respond to the Statements of Undisputed Material Facts submitted by
Evoqua and Travelers in support of their summary judgment motions, and therefore
those facts “are deemed to have been admitted by IGLSD.” IGLSD does not
challenge these significant procedural rulings on appeal.

              II. The Breach of Warranty Claim Against Evoqua.

       IGLSD claims that Evoqua breached its limited two-year express warranty that
the UV System equipment “is free from defects in workmanship and materials.” A
breach of express warranty claim under Iowa law “requires proof of a product defect
as defined in Products Restatement section 2.” Cummings v. Deere & Co., 589 F.
Supp. 2d 1108, 1118 n.22 (S.D. Iowa 2008), quoting Wright v. Brooke Group, Ltd.,

, 182 (Iowa 2002). Summary judgment is mandated “against a party
who fails to make a showing sufficient to establish the existence of an element
essential to that party’s case, and on which that party will bear the burden of proof at
trial.” Celotex Corp. v. Catret, 

, 322 (1986). “Evidence of a defect is
an indispensable element of any express or implied warranty claim.” Coop. Power
Ass’n v. Westinghouse Elec. Corp., 

, 1344-45 (8th Cir. 1995).

       In cases involving “complicated technical and scientific issues . . . expert
testimony is required to submit the issue of a product defect under Iowa law.”

. “Whether expert testimony is required
ultimately depends on whether it is a fact issue upon which the jury needs assistance
to reach an intelligent or correct decision.” Reed v. Chrysler Corp. 

,
226 (Iowa 1992) (quotation omitted). Here, with IGLSD precluded from presenting
expert testimony, the district court concluded that IGLSD could not prove that the UV
system was defective, an essential element of its warranty claim, because the issue
“involves sophisticated technology that kills bacteria in waste water through the use
of light that is literally invisible to the naked eye. Such technology is far beyond the
common knowledge and experience of the average layperson.” On appeal, IGLSD
argues that the court erred in granting summary judgment because it can present a
submissible case of equipment defect with lay witness testimony that “the UV
equipment failed to function frequently and in so many ways that it clearly was
defective and it wasn’t necessary for an expert to explain the obvious.”



                                          -4-
       Viewed in the light most favorable to IGLSD, the summary judgment record
reflects that the UV System often malfunctioned.2 However, the question is whether,
without expert testimony, IGLSD can establish that the UV System’s on-going
operational issues, such as the 2012 fire in Module No. 2, were caused by equipment
defects that breached the express warranty, rather than by improper operation and
maintenance of the complex system, improper storage during the winter, or other
possible causes.

      Even more significantly, the express warranty provided that IGLSD’s exclusive
remedy “is the replacement f.o.b. shipping point of the defective part or parts of the
material or equipment.” Evoqua’s Statement of Undisputed Material Facts, deemed
admitted by the district court, recited that “Evoqua was ready and able to address the
few remaining warranty issues on the punch list” but “IGLSD did not allow Evoqua
to repair or replace the few remaining warranty items.” This is confirmed by
Engineer Rasmussen’s May 2014 response to Evoqua’s rehab proposal in which he
advised that IGLSD “does not wish to go any further to repair the failed equipment.”
Buyer’s remorse, however justifiable, is not proof that the equipment had such serious
“defects in workmanship and materials” that IGLSD was justified in refusing
Evoqua’s offer to repair and replace, the exclusive remedy provided in the warranty,
and bringing an action seeking refund of the entire purchase price. Only expert
testimony could possibly justify IGLSD’s warranty claim for a remedy excluded by
the warranty. We conclude the district court properly granted summary judgment
dismissing IGLSD’s breach of warranty claim against Evoqua.




      2
       The Wastewater Treatment Facility only operated disinfection equipment
during warm weather months, so IGLSD’s conclusory assertion that the UV System
was nonoperational 57% of the time was not adequately explained and supported.

                    III. The Bond Claim Against Travelers.

      IGLSD also appeals the dismissal of its claim against Travelers under its
Performance and Maintenance Bond. The bond guaranteed the contractor’s full
performance of its obligations under its contract with IGLSD. Section 13.07 of the
contract obligated the contractor to correct, at no cost to IGLSD, “any Work [that] is
found to be defective” within one year after the date of Substantial Completion or any
longer period prescribed “by the terms of any applicable special guarantee required
by the Contract Documents.” If IGLSD had established that Evoqua’s UV System
was “defective,” the contractor and its bonding company would be obligated by
§ 13.07 to correct or repair or replace the defective work. But we have affirmed the
grant of summary judgment dismissing the claim of defective work.

        IGLSD argued an additional theory to the district court that became the focus
of its appeal. As the district court explained, quoting IGLSD’s contention:

             IGLSD [argues] that recovery against Travelers is [not] dependent
      on and/or limited to a breach of warranty claim[] against a supplier of
      materials for the project. The [contract] provides that the project
      engineer and the owner have the authority to reject work that they
      believe to be defective or that the Engineer believes will not produce a
      completed project. On May 12, 2014 the engineer and the owner
      rejected the UV equipment and ordered that it be replaced or that the
      cost be reimbursed. The contractor hired by Travelers did not comply
      nor did Evoqua or Travelers which Plaintiff alleges is a breach of the
      terms of the contract and the Bond.

The district court rejected this theory, concluding that Engineer Rasmussen’s
authority to reject work applied during “the actual construction phase,” which ended
when Rasmussen declared the project substantially completed on November 1, 2011.
Although § 13.07 extended the contractor’s obligation to repair or replace defective
work after Substantial Completion, the court reasoned that § 13.07 did not “extend

                                         -6-
the project engineer’s ability to reject work indefinitely beyond completion.” Rather,
the court concluded, “[t]o make a proper claim regarding completed work, IGLSD
must establish a construction, installation or equipment defect.” We agree.

        Engineer Rasmussen’s authority to reject work he “believes to be defective, or
. . . will not produce a completed project” is found in § 9.06 of the contract, part of
Article 9 entitled “ENGINEER’S STATUS DURING CONSTRUCTION.”
Rasmussen’s May 12, 2014 letter to Evoqua and Travelers was a response to
Evoqua’s proposal to complete warranty repairs with a substantial rehab of the two
UV modules. The letter did not state that the UV System was “rejected” and did not
cite § 9.06 of the contract; rather, it requested that the system “be removed from the
project and the cost of the initial purchase of the equipment be refunded to the
District.” IGLSD argues on appeal that the letter was a proper exercise of the
engineer’s power to reject work, a power limited only by his professional duty of care
and reasonableness. But that characterization is contrary to the plain meaning of
§ 9.06 and the letter itself. And the argument ignores the fact that the letter was not
sent until May 2014, months after expiration of Evoqua’s warranty and expiration of
the contractor’s two-year “guarantee and maintenance period” that is referenced in
IGLSD’s Notice To Bidders and the Travelers bond, but is not otherwise to be found
in the Contract Documents IGLSD placed in the record on appeal.

       The summary judgment record established that IGLSD considered rejecting the
UV system in 2010, well before the engineer certified Substantial Completion, but
chose not to do so. On November 17, 2010, Travelers and IGLSD sent Evoqua an
email warning that they were considering rejection due to installation delays. A July
2011 internal Travelers email reported that IGLSD’s engineer was “mumbling about
rejecting the system.” Instead, on November 1, 2011, Engineer Rasmussen certified
that “the UV disinfection equipment is now Substantially Completed and the project
can be finally accepted.” Under Iowa law, it is a “general rule that as to known
defects, acceptance of the work in the absence of fraud or mistake is a complete bar

                                         -7-
to recovery on the construction bond.” Elliott Consol. Sch. Dist. v. Busboom, 227 F.
Supp. 858, 862 (S.D. Iowa 1964). In these circumstances, we agree with the district
court that “IGLSD is unable to contort the contract/bond language to such an extent
that it could unilaterally reject the UV unit in 2014, without showing (through expert
testimony) some type of defect.”

      The judgment of the district court is affirmed.
