Thermador Appliance Repair in Denver

Thermador dishwashers run on the BSH platform, so the codes on the display are the same ones Bosch owners see. Most of them point at the drain side of the machine, and two of them you can clear yourself before calling anyone.

A Denver detail that changes the advice: much of the metro has moderately hard water. Scale builds up on the filter, the spray arms and the heater faster than the manual assumes, so a dishwasher that has never been descaled is the one that starts throwing drain and heating codes.

• E22: the filter is blocked. Pull the cylinder filter out of the sump, rinse it, seat it back until it locks. This one is on you, not us.
• E24 / E25: the drain pump is blocked or its cover is loose. Check the drain hose for a kink, take the pump cover off and clear whatever fell in. If it comes back after that, the pump itself is the problem.
• E15: water in the base pan has tripped the leak protection. Switch the power off and look for the leak. Sometimes it is a one-time spill from an overfilled detergent dispenser; if the code returns, there is a real leak and the machine needs a technician before it damages the floor.
• E09: internal heater fault. A power reset is the only thing to try; if the code stays, the heater or its control needs replacing.
• No code, just poor washing: check the spray arms for scale and food debris first, then the filter. If both are clean and glasses still come out cloudy, the circulation pump or the heater is not doing its job.

Freedom columns and the built-in bottom-freezer models are sealed into cabinetry, which is exactly why they need a technician who has taken one apart before. The refrigerator and freezer sections run as separate systems, so when one side warms while the other stays cold, the usual suspects are the evaporator fan on the warm side, an evaporator that has iced over because the defrost cycle stopped running, or the control board that manages both.

Ice makers are the other frequent call. Low output, small or hollow cubes and no ice at all usually trace to the water inlet valve, the fill tube freezing, or the filter and water pressure, and less often to the ice maker module itself. We check the cheap causes first.

A compressor that runs constantly without cooling, or that does not run at all, is a sealed-system repair. Before authorizing that on a built-in, it is worth a diagnosis: sealed-system parts often carry longer coverage than the rest of the appliance, so check your Thermador warranty card and the purchase date before deciding between repair and replacement.

Thermador kitchens cluster in the newer and higher-end parts of the metro, and that is where most of our Thermador calls come from: Highlands Ranch, Castle Pines, Lone Tree, Greenwood Village, Cherry Hills Village, Cherry Creek and Central Park in Denver, plus Golden, Arvada, Broomfield and Westminster on the north and west side. Same-day appointments depend on where you are and what is broken; when you call, tell us the model and the symptom and we will tell you the earliest realistic slot.
