Hi, My Bosch Logixx 8 is showing error F18 which I think means the filter is blocked. we have lost the manual so how do you get the filter out. Do we need to drain the machine first? Is there an online manual I can look at?


F18 is either the pump discharge is clogged or the machine is oversudsing. If it is oversudsing, make sure that you are using an HE detergent and use less detergent. (Make sure to note the minimum detergent line

To clean out the pump discharge, have a bucket ready for when you release the hose. First, set the cycle selector to Off and unplug the washer. Open the service door and remove it. Next loosen the screws and remove the protective foil. Remove the emptying hose from the holder and take off the cap. Drain the water from the hose. Replace the cap. Then carefully remove the pump cap and drain the rest of the water from the pump. Clean out any foreign objects from the area (housing, threads of the pump cap, etc). Make sure that the impeller can turn. Then replace the pump cap and tighten the screws (the handle should be vertical). Replace the emptying hose and the foil protector. Replace the service door and plug back in. Then fill the dispenser II with 1 liter of water and then start the Drain cycle. Let this water flow through to the pump.

The manual is available from Bosch. Go to http://www.bosch-home.com/us/WAS24460UC.html?source=search and click on Additional Documents . Then click on User Manual. This will redirect you to the correct page. Select your specific model and the language and click on the manual with the IU designation. The pictures to go with the clogged pump are on page 9 of the PDF.

The filters that can get blocked are in the water inlets. To clear those, turn off the water to the washer. Select a cycle and press Start/Pause. Wait 40 seconds then set the selector to Off. Unplug the washer. Then remove the inlet hoses. Clean and replace the filters at both sides of the hose. You will need pliers to remove the filters from the washing machine side. Then reconnect the hoses and check for leaks.

I hope this helps.
