Why does my Thermador dishwasher stop and won't drain or start?

Often water has reached the base pan and triggered the float switch. That shuts the cycle down to prevent flooding. We find the source of the leak, dry the base and reset the system.

Our builder-grade dishwasher in Indian Trail leaves grit on the glasses. Is it the water?

On town water, grit is more often food debris recirculating from a clogged filter or a weak drain. Clean the filter and run hot water at the sink before starting a cycle. If grit persists, a technician can check the drain pump and spray arms.

Is it worth repairing a ten-year-old dishwasher in a Stallings home?

It depends on what failed and how the tub and racks look. A drain pump or door seal on an otherwise solid machine is usually worth fixing, while a rusted tub or a failed control plus a worn motor may tip the balance. We tell you plainly which side your dishwasher falls on.

Thermador Dishwashers: What We Check First

Thermador dishwashers, including the Star Sapphire and related lines, are built on the same BSH engineering platform as Bosch dishwashers. They use a cylindrical filter in the base, a drain pump below a small cover, a circulation pump with an integrated flow-through heater, and a leak protection system with a float switch in the base pan. Many models offer StarDry, which uses a mineral called zeolite to help dry dishes, and third-rack cutlery storage.

Base pan float tripped by a hose, seal or suds leak
Circulation pump and heater assembly failing to heat water
Drain pump impeller jammed beneath the filter cover
Weakened hinge springs under heavy custom door panels

The full explanation, including what you can safely check yourself and when repair beats replacement, is in our Thermador dishwasher repair guide.

Daily Loads Wear Pumps and Seals

A dishwasher installed with the house and run once or twice a day piles up cycles quickly. In these neighborhoods the typical problems follow that wear: a drain pump that hums without moving water, a wash motor that weakens, a door gasket that seeps onto the floor, or racks with broken rollers that let dishes block the spray arms.

Water here mostly comes from municipal supply, so heavy sediment is less of a factor than food debris. That makes the filter the first thing to check. Turn the dishwasher off at the switch or breaker, pull out the bottom rack and rinse the filter assembly, then make sure the drain hose under the sink is not kinked where it meets the disposal.

Our technician runs the dishwasher, checks the fill, wash and drain stages, and looks for leaks under the tub. You get the diagnosis and the price before parts are installed, and the repair carries our 90-day parts and 30-day labor warranty.
