What commercial dishwasher brands do you repair?

We regularly repair Winterhalter, Classeq, Maidaid and Sammic commercial dishwashers and glasswashers. We cover other makes and models too — contact us to check whether your machine is supported.

How quickly can you attend a breakdown?

Response times depend on your location and engineer availability. Contact our team directly for current lead times and to discuss emergency callout options.

Do your engineers carry spare parts?

Yes — our vans are stocked with the most commonly required parts for commercial dishwashers and glasswashers, which means most repairs are completed without a return visit.

Do you repair glasswashers as well as dishwashers?

Yes. We service and repair commercial glasswashers, undercounter dishwashers, pass-through machines and rack conveyor dishwashers.

Can you repair a machine that wasn't purchased from GMSE?

Yes. We repair commercial dishwashing equipment regardless of where it was bought or who originally installed it.

What's the difference between a repair and a planned maintenance visit?

A repair is a reactive callout to fix a specific fault. A planned maintenance visit (PMV) is a scheduled inspection designed to catch issues before they cause a breakdown. Many operators use both — a PMV contract to reduce downtime and a repair service for when faults do occur.

Will I receive a report after the repair?

Yes. We provide a written service report after every visit, covering the fault found, work completed, parts used, and any recommended follow-up actions.

Do you offer maintenance contracts for commercial dishwashers?

Yes. GMSE offers planned maintenance contracts for single machines, multi-machine sites and multi-site operations. Regular servicing also helps maintain manufacturer warranties and reduces the risk of unplanned downtime.
