Identifying the Problem

Clearing the Drain Filter
The drain filter is often the culprit behind drainage problems. To clean it:

2. Unscrew the filter cap and remove the filter.
3. Rinse the filter thoroughly under running water to remove any food particles or debris.

Checking the Drain Hose
A kinked or blocked drain hose can prevent water from draining properly. To inspect the hose:
1. Disconnect the drain hose from the dishwasher.
2. Check for any kinks or obstructions.
3. If the hose is kinked, straighten it out.
4. If the hose is blocked, use a wire or pipe cleaner to clear the blockage.
5. Reconnect the drain hose to the dishwasher.

1. Remove the drain filter and hose as described above.
