Knowing the causes and solutions can help you keep your dishwasher clean and efficient. Here is a step-by-step guide. It will help you fix the E22 error code.

Understanding the E22 Error Code: Causes and Solutions

If your dishwasher’s filter or drain is blocked, it will display the E22 error code. This prevents proper drainage. The filter traps debris, like food particles and residues, from the wash cycle. Over time, these particles can build up in the filter assembly, causing it to become clogged. This blockage can cause standing water in the dishwasher. It may also lead to longer wash times, unusual noises, or a bad smell at the end of the cycle.

Step 1: Clean the Dishwasher Filter

To begin addressing the E22 error, you must first clean the filter. Here’s how:

1. Disconnect the dishwasher from the power outlet. Or, turn off the power at the circuit breaker. This is for safety.
2. Remove the bottom rack and bottom spray arm by gently lifting them out of the dishwasher. This provides easy access to the filter assembly.
3. Turn the filter knob left to disengage it. Then, pull the filter out carefully.
4. Inspect the filter for any food particles, debris, or residue. Check for any damage that may must a replacement or repair.
5. For a thorough cleaning, rinse the filter under warm running water. Use a soft-bristled brush and dish soap to scrub away any stubborn debris. Make sure to clean the filter screen thoroughly.
6. Once the filter is clean and free of debris, allow it to dry completely before reassembling. Reattach the filter cap and ensure the screen is in place.
7. Return the filter to its original position and turn it clockwise to lock it securely. Reattach the bottom spray arm and return the dishwasher rack to its position.
8. Reconnect the dishwasher to the power supply and run a test cycle to check if the E22 code is cleared.

Step 2: Check and Clear the Drain Hose

If the E22 error persists, check the drain hose. It is vital for removing water from the dishwasher. Here’s how you can clear a blocked drain hose:

1. Disconnect the dishwasher from the power outlet and turn off the water supply.
2. Remove the kick plate (or toe kick) at the base of the dishwasher to access the drain hose.
3. Use a pair of pliers to compress the clamp securing the drain hose to the dishwasher. Place a bucket or towel underneath to catch any residual water.
4. Check the drain hose for obstructions. Then, run high-pressure water through it to clear any build-up.
5. If a blockage remains, use a long-handled tool to gently push out the debris. Be cautious not to damage the hose.
6. Once cleared, reattach the drain hose to the back of the dishwasher. Then, replace the kick plate with the appropriate screws.
7. Reconnect the dishwasher to the power supply and check if the error is resolved.

Step 3: Inspect and Clean the Drain Pump

The drain pump is vital. It expels the dishwasher’s wastewater into the plumbing. A blocked or malfunctioning drain pump can also trigger the E22 error. Follow these steps to inspect and clear the drain pump:

1. Turn off the water supply and disconnect the dishwasher from the power outlet.
2. Locate the drain pump, usually at the front of the appliance. Then, carefully disconnect the hoses from the pump.
3. Check both the inlet and outlet ports on the pump for any obstructions. Make sure the impeller is moving freely.
4. Use needle-nose pliers to remove any hard-to-reach items that may be blocking the pump.
5. After confirming the pump is clear, reattach the hoses and reassemble the dishwasher.
