My boch exxel 1600washer showing F18 so I manually removed the water but and removed 20p from drain however pump now only making a low buzzing noise is it done for

If hoses clear and filter not blocked, can only be pump fault

it could either be a bad door switch or something stuck in the pump or a bad pump.if you set it to drain/spin will it drain out the water or does it buzz there?if it does drain i'd have to say you have a bad door switch.the model number you sent doesn't come up,you can unplug the machine,remove the hose that goes to the pump or run it before you unplug it and see if it's the pump making the sound or if the center of the pump can be removed to clean out the pump and check the pump for coins and junk,use a shop vac and vac out all the water in the tub and then lossen the hose or center of pump until water starts to leak out and vac it up as it comes out,check the pump and put it back together,add some water with a bucket or something and see if it drains out,if it doesn't drain and it sounds like the pump is making the noise you have a bad pump,if it buzzes and it's not the pump change out the door switch.the buzzing is electrical,things that could make this sound are the motor,the solenoids on the water valve or the door switch,if you can do some checks like see if it drains or try to find where the noise is coming from would be helpful.good luck and i hope this helps you out.

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.

Drain fully,remove the pump filter and see if you can remove the blockage.

Hi,

F18 means pump is blocked or broken, clean filter first, no result change then you have to change the pump.

I also had this problem - the machine was full of water and it flashed up F18. I had to drain the water out of the machine using the small pipe located next to the drain filter. There was loads of water to drain out. I used my oven roasting tray which was perfect for the job. Then I undid the screwcap filter. There was a lot of really black water that came out, along with about two pounds worth of coins and some hairgrips. Now my machine works perfectly !

thank u

check pump strainer

Hi, there may be an obstruction in the pump housing that is causing the motor to freeze or, the impeller may be stripped and , jamming the pump. this will cause the hum you are hearing. the best way to inspect is to , extract the drain pump by, removing
the bottom drain filter housing or sump. manually
move the pump impeller to self it is moving freely. if the impeller is stripped, it will not be able to produce the draining surge necessary to pull the water out.

If the impeller is fine and, there are no obstructions visible, this will confirm pump failure.. replace the pump in this case


Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

take the front bottom panel off. inside there is a drain pump. you need to remove filter from drain pump its look like a knob. be careful because their is water inside your drain pump so use some big thing for water. clean your filter. put filter back tight. i hope will solve your problem.

This noise is probably the pump trying to start but will most likely be obstructed.Drain the machine manually by lowering the drain hose into a bucket or bowl and then remove blockage.
