Bosch Dishwasher Error E08

How to Fix E08 Error (Step-by-Step) Press the ‘On/Off’ button to turn the dishwasher off and cancel the current cycle. Open the dishwasher door and check the position of the gray drain hose located under your sink. The drain hose must be looped up high, with the top of the loop secured as close to the underside of the countertop as possible. This creates a ‘high loop’. A proper high loop prevents water from the sink drain from flowing back into the dishwasher and also stops water from siphoning out of the tub during a cycle. If the hose is not looped high enough, reposition it and secure it in place with a zip tie or clamp. After confirming the high loop, close the dishwasher door, select a new wash cycle, and press ‘Start’ to see if the error is resolved. Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Bosch Dishwasher Bosch Dishwasher Error E08: 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 fill path: water supply, inlet screen, hose position, float or level sensing, inlet valve 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. Still Not Working? If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure. Browse all Bosch error codes: Bosch Error Codes
