What to Check Next on This Bosch Dishwasher
Bosch dishwasher symptom: Use the symbol or code as a starting point, then match the repair path to what the dishwasher is actually doing.
- Confirm whether the display is a normal cycle/status symbol or a recurring fault that stops operation.
- Check water supply, filter, sump, spray arms, drain path, and door latch before replacing electronic parts.
- If the same problem returns after basic checks, inspect the matching sensor, pump, heater, wiring, or control path based on the symptom.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
