Dishwasher running but no water is being pumped in.
There was a layer of water at the bottom of my dishwasher 2 days ago. I followed some online instructions and opened the left hand screw on the metal plate and managed to get some pips and a small piece of glass out of the small filter/grate.
However, now when I switch it on, the engine sounds like it's running, but no water is pumped in and the plates are dry.
I've read that it might be caused by the 'floater' and that the 'floater' needs to be in the 'up' position. BUT...what is a floater and where is it?? What do I need to do to get to it (unscrew screws etc).
I don't know what model my Bosch is as I can't find a model number anywhere on the machine - it's built into a cupboard.
Re: Dishwasher running but no water is being pumped in.
The model number is laser etched into the top of the inner door if you shine a torch across the top you should be able to read it sometimes they are quite faint,all bosch dishwashers are fitted with an anti flood device triggered by water in the base appliance will only drain out and do nothing else the water needs to be drained out. the easiest way is to tip the machine backwards with a towel on the floor to collect the water( will be about a pint!) or if you leave it stood in a warm kitchen after a few days the water will evaporate and appliance will start up again.

Hi, there will always be some water in the bottom the tub. This is called the sump. When your pump stops draining, all the water that's up in the hose will drain back into the sump. You failed to tell me how much water is there. If a small amount then it's normal, however if it's a large amount that covers 1/2" or so then you indeed have a problem and snaking out the lateral should clear it up.
I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying... Dishwasher Spray Arms not Spinning
You'll need to get the water out of the bottom of the dishwasher - a wet vac usually works the best.
Remove the bottom rack and check the pump inlet screen in the bottom of the dishwasher for debris - it would be best to remove the screen and look for anything that may be preventing water from entering the pump.
The sink, at least the side where the dishwasher drains to be sure it isn't plugged
The discharge hose from the dishwasher to be sure it isn't obstructed somehow - you may to remove it to be sure. Check the discharge line check valve assembly to be sure it isn't stuck with something
You could have a control board issue, but if the pump is running, it should pump.
Check for hose kinks or food plugging drain hose. Start at the drain port exit. Check the check valve and drain hose for debris. Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle. Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise If you have recently installed a new garbage disposal, check knock-out plug at connection.
Check pump impeller for damage. Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.
1. not enough water gets into the dishwasher. open the dishwasher 3-4 times during cycle, you should see some (quite some) water at least once, if not - check water valve, water level float and water pressure. 2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller. 3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.
I had the same problem. The motor is working (humming) and my dishwasher goes through the whole cycle without water. I googled it and found it on a website. Sorry I don't remember which website. Basically, it said to put some hot water in the bottom of your dishwasher and add some citric acid. I added 2 small packets (2 oz each) and filled the bottom of the dishwasher with hot water until it covered the motor or the drain of the dishwasher and left it overnight. The next day my dishwasher started and ran perfectly fine. That was over 4 months ago and I have not had any problems.
hi the larger motor housing underneath the unit is what moves the water around to wash, the smaller pump is the drain pump, if you don't hear that running it is likely in need of replacement. check your paper work for warranty, if it's out of warranty try to find a deal online and it's relatively easy to replace
I've just (as of 10 minutes ago) had the same problem. I followed the advice given elsewhere in this forum and removed the bottom cover - water running out so needed a big towel to mop it up. I stood the machine upright and restarted it - no problem! it started straight away.
The question now is where is the water coming from? It seems there is obviously a leak somewhere and water is gathering in the undertray setting off the microswitch.
