⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: E18 Difficulty: Hard
Problem: Low water level or issue with water flow.
How to Fix E18 Error (Step-by-Step)
- Turn off the dishwasher by pressing the power button, then shut off the circuit breaker dedicated to the appliance. For safety, also close the main water supply valve, usually located under the sink.
- Check the water supply hose connected to the back of the dishwasher. Ensure it is not bent, kinked, or crushed, as this can restrict water flow.
- Place a shallow pan and a towel under the water inlet valve connection at the dishwasher. Unscrew the supply hose and inspect the small filter screen inside the valve’s port. Clean any debris or mineral buildup from the screen using a small brush.
- To inspect internal components, remove the screws holding the front access panel at the bottom of the dishwasher. The water inlet valve (part 00631200) is typically on the front left side. Check its wire connections and look for any visible cracks or damage.
- Locate the flow meter (part 00620774), which is often near the inlet valve assembly. Ensure its wiring is secure and there are no visible signs of damage or blockages in the connected tubes.
- Inside the dishwasher, remove the bottom rack and unscrew the filter assembly in the sump area. Clear any food debris and check the drain pump cover. Remove the cover (it may twist off or be held by a screw) and inspect the drain pump impeller (part of 00642239) to ensure it can spin freely and is not blocked by foreign objects.
- If these checks do not resolve the error, the inlet valve, flow meter, or drain pump may be faulty and require electrical testing with a multimeter. Due to the complexity and risk of water damage, it is recommended to have a qualified service diagnose and replace the necessary components.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
