Pump Runs On After Water Is All Drained Out?

Today our Bosch dishwasher started doing this. When started, water comes in and you can hear the pump running. But when it drains, after the water is gone the pump runs on and on...forever, it seems. Any ideas?

Re: Pump Runs On After Water Is All Drained Out?

If the cycle does not stop draining that is usually because of a faulty water level switch that controls the water level in your appliance.
The faulty sensor cause the machine to think that there is still water inside, even when water has drained completely.
Check if the floating sensor is stuck or faulty.
Some machine may use a membrane switch instead of a floater.

Bosch classixx dishwasher starts cycle then says " check water" and then seems to do same thing again and again, pumping water in and draining it again

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 (white plastic disc with two wire connection tag). 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.

Bosch she45mo6uc/52. came home today and is has a loud hum. looks like it never got water in. the dry soap is just laying inside.

The humming noise is either from the pump motor or the water inlet solenoid. One of them is stuck. Take the mopboard plate off the front of the dishwasher and look for the solenoid. It will be a cylinder with two wires attached stuck onto a box in the water line. Start the dishwasher and touch the solenoid with a finger (naturally not the electrical terminals). If you feel it vibrating in time with the hum but do not hear the water running in, the valve is stuck closed. In this case the solenoid may rapidly get hot; that's why you just touch it with a fingertip.

If water comes in and the big motor in the middle starts humming as soon as the fill is complete, then the pump is jammed or the motor bearings are frozen. You'll have to disassemble the pump (from inside the tub) to see what's going on. You should be able to freely rotate the pump impeller and the motor shaft by hand (this is inside the pump; don't confuse it with spray arm, which is spun by reaction from the water spraying out rather than a mechanical connection to the pump motor).

Another possibility is that the water fill level switch is hung up and signaling a complete water fill when the unit is still dry. If this is the case, when you start the dishwasher you may hear the water solenoid briefly, then the pump will start running immediately. Since it has no water, it will just spin at full motor speed. A quick test for this is to pour about a gallon of water into the dishwasher, then close the door and let it run. If it runs normally until it gets to the rinse cycle, then it's either the level switch or the solenoid valve. (Be sure it isn't a pump problem first or you'll have to get the water out while you can work on it!)

Water enters dishwasher,the unit seems to go on hold, then it will drain. Nothing else works as far as the washing cycle or any thing else.

this could be that the main pump id defective, once water enters the main pump does all the work to throw the water around and clean, once that is done the water is drained etc.
so when you dont hear anything this indicates that the main pump is not running.

supect this part first.

I hope this was useful

Bosch Dishwasher SHX46A05UC/23 - No Water

Sounds like your recirculating pump is clogged If it is water can't get up enough pressure to turn the sprayers.
You'll need to start pulling parts out of the bottom inside to get to that pump. I don't work on a lot of Bosch, but that sure sounds like it to me. I see this a lot. Hope this helps...

Water does not drain

For the water to drain, the controller must send power to the water pump and the solenoid (drain) valve.
If you hear the pump running when it should be draining then the controller and pump are working and the solenoid is bad (usually the case).
If you don't hear the pump running during the drain mode, then either the pump is bad or the controller is bad (not sending power to the pump).
Also, check that you do not have debris inside the dishwasher where the water drains. This is around the spindle in the bottom of the dishwasher cabinet where the spray arm comes up.

If this helps you, please select YES to one of the first two ratings questions. Thank you, and Good Luck.

Drain pump runs continously

Sounds like you have a leak under the unit. There is a float in the bottom that turns the pump on when it has water in the lower pan. It won't let any water fill until it is dry.

Bosch SHX46A (6 years old) Selected regular cycle, pressed On and closed door. Cycle did not start normally. Pump runs, but no water is coming into the DW. I confirmed the water supply line is turned on....

From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump.  It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck!  Please report back what you find, OK?
