How to Check your drain pump filter for foreign objects:Most likely, this issue will be the cause of a clogged drain filter. Use my procedure below to help locate and clean this filter.
First, you will need to unplug your unit and shut off the rear water faucets that feed the unit.The pump has a clean out filter located at the front, behind the lower section of the front panel, that allows for the removal of large objects that may have passed from the basket. You will need to remove the front panel to access this large object filter device. Now, Once you have located the drain filter cap; Push twits and pull out the filter cap that is visible. Clear out any debris and wipe the filter and the surrounding area with a mild detergent. If needed, wear gloves and use vinegar or bleach to remove odors, mold and mildew. Rinse the parts completely, if possible. Next; Remove the drain hose and clean it with a mild detergent or warm water. If necessary, again use vinegar or bleach to remove odors and mildew. Completely purge this hose. Once the drain hose has been purged, Reconnect the drain hose and filter. Next; Place the front panel back on the unit. Reconnect the inlet hoses and plug in the unit and turn it back on for a test run. If the cleansing dose not produce positive results, replace the drain pump.
