I recently tried to use the detergent feature on my Kärcher pressure washer, but even though the detergent reservoir appears to be full, no detergent is being dispensed. What should I do?

There are a few things you can try to fix if your Kärcher pressure washer isn't dispensing detergent even though the reservoir looks full.

• Make sure the system isn't clogged. To clean the detergent filter, take it out (see your user manual for instructions), wash it with warm water and soap, and make sure it's dry before putting it back in. Also, check the detergent suction hose and nozzle for any blockages. If there are any, carefully remove them with a thin wire or pipe cleaner.

• Make sure the connection is correct. Make sure the detergent reservoir is attached properly and that there are no connection points that are loose or leaking. Also, make sure that the detergent selection settings on your Kärcher model are set to use the detergent if it's needed.

• Think about how well the detergent works with other things. To avoid clogs or foaming problems, make sure you only use detergents that are approved by Kärcher. For advice on which detergents to use, look in your user manual or talk to an authorized dealer. If you are using a highly concentrated detergent, make sure you dilute it correctly according to the manufacturer's instructions so that it works well without overpowering the pressure washer.
