Bosch Repair · Bay Area

Bosch dishwashers are the workhorse of the lineup and most of the call volume. 800 Series and Benchmark units share the same recirc pump and drain pump as the 500 Series. When the pump bearing gets noisy or the drain pump grinds, the customer hears it before they see a code.

The Crystal Dry zeolite tank on Benchmark dishwashers can fail with a partial dry cycle. Dishes come out wet on top, fine on the bottom, no error code shown. The fix is the heater-tank module replacement, not the door vent fan as the YouTube videos suggest. We test the zeolite tank temperature rise on a service cycle before we order parts.

Bosch 800 Series French-door refrigerators have an evaporator-fan icing issue in the freezer compartment. The defrost-cycle heater runs but the drain line freezes shut, water pools, and freezes the evap fan into the back wall. Symptom is loud fan rattle for a week, then warming fresh-food side. We pull the back panel, thaw the line, replace the drain heater and the fan motor in one trip.

Induction cooktops throw an F47 or E5 code for IGBT power-module overheating. Nine times out of ten it’s a blocked cooling-fan vent under the cooktop, not a board failure. We pull the unit, vacuum the fan intake and the heat sink, and verify the IGBT temperature with a thermal probe. Saves the customer a $900 board on a $5 dust problem.

Wall ovens use the same European-style hidden bake element. When it fails, no glow from the bottom and the oven cycles cold. Element replacement is two hours and one visit if we get the model number from you ahead of the appointment.
