Cleaning a dishwasher filter

To clean the filter, you must first remove it. The filter unit can be removed by unscrewing the filter cylinder at the base of the dishwasher and lifting the unit out. It can then be cleaned under the tap before being replaced. Before loading dishes into the dishwasher, always ensure that all food debris is scraped off beforehand. If this is not done, the debris can build up and possibly block the filter, spray arms and pump. If the pump is blocked, waste water cannot be pumped out of the dishwasher and could cause the programme to stall. For more information on unblocking the pump, click the link below.

Step by step guide

1. Remove the dishwasher rack.
2. Unlock the filter unit found at the base of the dishwasher and carefully pull it out. Separate the unit by carefully unscrewing the cylindrical filter first.
3. Clean both filters under running tap water. You can use a small brush to gently clean the inside of the filter and remove smaller pieces of debris. Do not use anything abrasive as this can damage the filter.
4. Reassemble the unit and put it back into the dishwasher.
5. Twist the filter to lock it into position until both arrows line up.
