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.

We just moved into a Pineville rental and the dishwasher leaked on its first run. Why?

Seals and pumps can dry out while a dishwasher sits unused during a vacancy, and the first cycle reveals it. Close the supply valve under the sink and report it to your landlord. A technician can check whether a seal, valve or hose is at fault.

Does the drain hose height matter in an older Pineville kitchen?

It does. Without a high loop or air gap, dirty water from the sink or disposal can flow back into the dishwasher. When we service a dishwasher in an older kitchen, we check that connection and point it out if it needs correcting.

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.

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.

Tight Openings and Rental Turnover

In older Pineville houses, the dishwasher was often added years after the kitchen was built, so the opening can be narrow, the drain may connect to a disposal replaced since, and the supply line may be an aging copper connection. Apartments and townhomes usually have a standard builder model in a standard opening, which is simpler to pull out and service.

A dishwasher that sits unused between tenants can come back with stiff seals, a sticky inlet valve or a dried pump seal that leaks on the first run. In occupied units, a clogged filter and a drain hose without a proper high loop are behind many standing-water complaints.

Clean the filter, run the disposal before starting the dishwasher, and check the cabinet floor for moisture. If water is on the floor, turn off the breaker and close the supply valve under the sink. We diagnose the pump, valve and seals and give the owner the price before repairing.
