Re: not emptying or filling
The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it.
The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

I pulled the dishwasher , on the left side if it about halfway back down near the bottom you will see a plastic resovoir like , it has two hoses hooked to it , I took it off being careful not to break the seal, then I used a pipe cleaner to get the crud off of the float that is inside the flat looking plastic container . it works like a champ now !
The light can come for a few reasons. Not emptying, not filling, over filling or water leaking into base. Probably jug impellor part number (424099) from espares, buyspares or bosch direct. No fix unfortunately, this problem manifests as unit starts to fill and motor does not switch on. Eventually the unit overfills and the pump and fill start to alternate and check water light comes on. If this is the fault then this part is the solution it runs in line with the inlet valve and side fill chamber, take the left side panel off (looking from the front) it is tucked away behind the hoses bottom left. Check water light can also come on if the unit is not pumping, if this is the case, repost and I will try and talk you through clearing this fault.
The reason only the pump runs anytime its powered up is because the flood detector has detected water in the base of the dishwasher and until that water is gone only the pump will run.That flood detector is (when looking at it from the front) is in the left front corner,its a styrofoam disc with a rod in the center of it and has floated up activating the flood switch on the letf side wall where the water enters the tub (can be seen on the left side with side panel removed) if thier is no water in the base frame perhaps some foreign object has wedged itself under the sytrofoam disc holding it up. Until the water is out of the base frame only the pump will run as long as the flood switch is tripped.
Possible things that will make water be in the base frame are, oversuds from too much detergent a leak of any component or hose a defective water level switch allowing it to overfill
If you remove the lid and looking at the front of the d/w take of the lefft side panel, at the right bottom on the side you should see a pressure chamber with some micro switches and a red lever. This is possible blocked along with the hose that is attached to it (to the right, behind the chamber) clear them both and retest with the side panel off to check for good flow and to make sure you have not created a leak.
Error caused by a leak which fills the plastic base tray and operates pressure switch to stop machine working, easy to check by removing metal panel under door (2 screws) and feeling for water. Make sure its switched off first. If pool of water found like i found dry out remove side panels and run on a short cycle to locate leak. Mine was from a joint with a oring on the RH side of the m/c which was a odd size decided to silicone joint which worked.
pump has a blockage-mine was a piece of cloth(fibre) that was stopping the pump turning. Fixed in about 10 mins after i had emptied the water.
Disconnect (electrically) the dishwasher and lay on right hand side-undo bottom cover (2 screws) and remove (mind earth strap) Drain pumpcan be removed by unclipping pump elctromagnet (fiddly) and sliding off.
Now study pump body to determine which way to turn to undo.The pump is plastic and held in position by the plastic molded base-The pump spigot needs to be eased over this stop as the pump is turned.
The assembly can now be remoced for examination/replacement.
Replace as reverse-do not forget the polystyrene float that will have come off(probably).
Hope this helps
Typically this means that there has been a water leak of some sort and there is water in the lower base pan. This is the large white plastic base that the dishwasher sits on.
If you remove the toe kick and look back past the fill valve on the extreme left side of the dishwasher about 6 to 8 inches from the front you will see a red stick that goes straight up and down. This is a mechanical linkage that activates the drain feature. Be careful as there are live connections here.
This stick rests on a round piece of Styrofoam that acts as a float. If there is water present it will cause the stick to lift and the dishwasher will go into drain. The source of the leak will have to be isolated and corrected. Most likely it is the fill float assembly as referenced at the end of this post.
If the stick is not in the upright position then there is possibly an issue with the switch mechanism itself.
You will have to pull the dishwasher out from beneath the cabinet and remove the panel covering the left hand side. If it is a full panel then there are a couple of screws holding it on from the front through side trim as viewed when the door is open if it is a half panel then it can be removed by removing the large torx screw on the lower right as seen when facing the panel.
If there is a problem with the switch then the entire mechanism should be replaced.
Try the following link to a picture for reference. It is upside down as compared to the installed one:
there are three or 4 possibility's here remove the kick plate make sure the water valve is plugged up make sure the water is turned on make sure the safety float hasn't slipped off the micro switch that's the dome shaped object in the tub the micro switch is underneath next when you first turn it on do you hear the pump motor run check theese and let me know
It sounds to me like the base safety float has been activated. This will cause the unit to cancel the program it is in and activate the drain pump, hence the "run" that you hear, but no water.
You need to remove the lid and two side panels. If you see water inside the base, you know that the safety float switch has been activated.
Remove plug from outlet and empty water from base (by tilting to left side and using sponge to syphon water)
Restart unit and check where water is leaking from. Usually from a filling hose not correctly/tightly fitted; leaky inlet valve; leaky heater asembly.
Hope this helps!
