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.

The dishwasher in our older Rock Hill kitchen leaks from the front. What causes that?

A worn door gasket, an unlevel install or the wrong detergent producing too many suds are the usual causes. Check that the unit sits level and use only dishwasher detergent. If it still leaks, we inspect the gasket, the tub and the door hinges.

Our rental dishwasher near downtown Rock Hill won't drain. Can you come while the tenant is home?

Yes. Many of these calls turn out to be a clogged filter or a blocked drain hose, which we can often clear on the spot. If the pump has failed, we quote the part to the owner before replacing it.

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.

Retrofits into older cabinets

Plenty of older Rock Hill homes had a dishwasher added during a kitchen update, sometimes into a space that was not built for one. Drain hoses run long distances to the sink, supply lines may be old, and the unit may not be anchored or level. Those details cause leaks at the door, kinked drains and water left in the tub after the cycle.

Start with the simple checks. Clean the filter in the bottom of the tub, run the kitchen tap until the water is hot before starting a cycle, and confirm the drain hose has a high loop under the sink. If water appears on the floor, turn off the dishwasher's breaker and the valve under the sink before anything else.

What a technician does on the visit

Rock Hill's municipal water comes from the Catawba system, so cloudy glasses are more often a rinse-aid or detergent issue than a sediment problem. When the machine itself is at fault, we test the drain pump, inlet valve, heater, float switch and controls. We tell you the cause and the price first, and if the tub or door frame is too far gone, we say that a replacement is the better call.
