- Switch the dishwasher off and open the bottom filter area.
- Remove the filter assembly and rinse it under running water.
- Clear any food debris, labels, or glass fragments from the sump and filter housing.
- Reinstall the filter correctly and rerun a short cycle.
e22 usually means the dishwasher has detected restricted flow caused by a blocked filter area. Until the blockage is cleared, wash and drain performance can both suffer.
- Cleaning only the visible mesh and not the full filter assembly.
- Reinstalling the filter loosely so water can still circulate incorrectly.
- Ignoring labels, seeds, or glass fragments trapped below the filter.
Book service if e22 comes back immediately after a thorough filter clean, because a deeper blockage or pump issue may still be present.
- Turn the appliance off once, let it settle or cool if needed, and then restart it cleanly.ExpectedYou rule out a one-off interruption without hiding a repeat fault behind constant resets.
- Write down the full code, any flashing lights or symbols, and the exact stage where the appliance stops or behaves differently.ExpectedYou know whether the code appears at startup, mid-cycle, during heating, after draining, or during another specific stage.
- Inspect only the user-accessible items that match the symptom: filters, vents, trays, water containers, doors, drawers, removable consumables, or other parts the manual says are safe to check.ExpectedYou clear the easy homeowner-safe checks without opening covers or touching wiring.
- If e22 returns immediately or in the same stage again, stop repeated resets and move to model-specific support or repair triage.ExpectedYou avoid wasting time on blind retries when the pattern is clearly repeating.
The safest working diagnosis is that the code is tied to the subsystem named in the summary plus the conditions that feed or monitor that subsystem. You do not need to guess the exact failed part before you decide whether the pattern is stable and repeatable.
- The monitored part, sensor, switch, or control path may be out of range or no longer reporting a stable reading.
- A blocked, overloaded, dirty, or badly seated user-serviceable component can trigger the same code even when the core part has not failed.
- Recent interruptions such as a power cut, leak, filter clean, move, or incomplete reassembly can make a stored fault return in the next cycle.
- Photograph the full display and the product label or rating plate.ExpectedYou can confirm the exact model and avoid support or parts quotes against the wrong product variant.
- Note whether the appliance was idle, starting up, heating, filling, draining, cooling, or finishing a cycle when the code appeared.ExpectedYou have the timing detail that usually matters most in fault triage.
- Write down any recent changes such as a power interruption, filter clean, leak, unusual noise, smell, moved installation, or repeated manual reset attempts.ExpectedSupport can separate a recent event from a longer-running repeat fault faster.
If e22 returns after one clean restart and the user-accessible checks above, treat that as a repeat fault. The safest next move is to compare the model hub, confirm the official manual-safe checks for this device, and then escalate with a clear symptom record instead of opening panels or replacing parts blind.
