What to Check Next on This Bosch Dishwasher Bosch Dishwasher Error K: Use the code, light, or symbol as the starting clue, then confirm what the dishwasher actually does before ordering parts. 1. Turn power off before opening panels, reaching into the sump, touching wiring, or checking the pump, heater, valve, sensor, latch, or control area. 2. Confirm whether the display is a normal cycle/status symbol or a recurring fault that interrupts filling, washing, draining, drying, locking, or control response. 3. Start with the wash path: filter, sump debris, spray-arm movement, circulation-pump sound, wiring, and control output. 4. Clean the filter and sump, check spray-arm movement, verify water supply, inspect the drain hose and sink connection, and correct any visible blockage before replacing parts. 5. Run a short test cycle and watch where it fails; the exact stage matters more than the displayed word or symbol by itself. 6. Replace a part only after the same symptom repeats and the model-specific checks point to that part category. Match any replacement to the complete Bosch model number on the door tag. If the issue returns after these checks, match replacement parts to the complete Bosch dishwasher model number from the door tag. The same display clue can point to different components depending on the exact model and when the failure appears.
