The three Thermador dishwasher lines
Thermador sells three dishwasher lines. They are the Emerald, the Sapphire and the Star Sapphire. The Star Sapphire sits at the top. Many models have a third rack called the Chef's Tool Drawer. Some shine a light on the floor, called PowerBeam, to show the cycle is running. We repair all three lines. Thermador is owned by BSH, the group behind Bosch, so many parts are close cousins. See our Thermador repair overview for the brand's other products.
Standing water in the bottom of the tub
A dishwasher that will not drain is our top Thermador dishwasher call. Thermador's own guide names three causes. The filter is dirty. The drain pump is blocked by debris. Or the drain path is blocked at the disposal or the air gap.
The filter is a job you can do. Twist it out of the tub floor. Rinse it under warm water and scrub it gently. Then lock it back in.
Still see water with a spotless filter? Then the pump is next. A glass chip or an olive pit can lock its blades. Sometimes the pump motor has burned out. The drain hose also needs a high loop. Thermador says the loop should sit 20 to 50 inches above the floor. Without it, sink water can run back into the tub.
Dishes that come out wet
Thermador's drying system is called StarDry with Zeolite. Zeolite is a mineral that soaks up moisture and gives off heat. It sits in a sealed box in the base. It does not wear out in normal use. But the parts around it can fail. A fan moves air through the box. A heater dries the mineral out for the next load. If either one quits, dishes stay wet and the cycle may run long.
Check the rinse aid first. An empty rinse aid tank is a listed cause of poor results and long cycles. Plastic also dries worse than glass in any dishwasher.
No water, long cycles and other faults
- Will not fill. The valve under the sink may be closed, or the supply line is kinked. If both are fine, the inlet valve on the dishwasher has likely failed.
- Cycle runs very long. Thermador says cold incoming water is a cause. Run the hot tap at the sink before you start.
- Leak at the door. Run a finger along the gasket to feel for splits or crusted bits. Extra soap foams up and the foam creeps out past the rubber.
- Water in the base pan. A float switch in the base stops the unit when it gets wet. We find the drip that tripped it.
- Dead display. On top control models the display only lights with the door open. If it stays dark, the control board or door latch switch needs a test.
Booking, price and the repair itself
Our site takes dishwasher bookings around the clock. Phone staff work 6 AM to 9 PM and skip no days. Most Thermador owners see a tech before the day ends. He starts a short wash and watches each stage. Then he tells you what broke. Finding the fault costs a homeowner $79. That $79 is erased once you green-light the fix. Your quote is one firm figure with labor and parts rolled in. It reaches you ahead of any wrench work.
One family has owned A+. The shop is independent and takes no orders from Thermador. Every tech we send is background checked, licensed and insured. Our 30-day repair warranty covers the work.
Fixing an older Thermador dishwasher or buying new
Fixing wins far more often than not. Drain pumps, inlet valves, door gaskets and latches are modest repairs. A Thermador often has a custom door panel that matches your cabinets. A new unit means fitting that panel again. Replacing makes more sense when the tub leaks at a seam. The same goes for a machine that loses its board and wash motor in one go.
