Dishwasher stops with F08, often related to heating or drying phase; may also show steam but poor drying performance.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety: Always disconnect from mains before opening the door panel or accessing the control board.
Preliminary checks:
- Confirm that the heater element itself is not shorted to earth using a multimeter (insulation test if available).
- Inspect heater wiring for chafing where it passes through the base or side panels.
Control board inspection:
- Remove the inner door panel to access the control module.
- Visually inspect the heater relay/triac area for burn marks, cracked solder joints, or melted plastic.
- Gently press on large components to check for loose solder joints.
Action:
- If the heater tests good but F08 persists, the control board is usually the failed component and should be replaced as a complete unit.
- Do not attempt to bypass the relay or hard‑wire the heater; this is unsafe.
After replacing the PCB, run a full hot cycle and monitor for correct heating and completion without errors.
