Wash motor does not run: Inlet/Drain error

The wash motor does not run. Water fills the base of the dishwasher and after that the Inlet/Drain light flashes. If you restart the machine, it first drains the water and then refills it before flashing the Inlet/Drain light again.

There is no problem with the inlet or outlet. I have checked to see if any of the pipes are blocked and there seems to be no problem there. I haven't removed the main pump to see if it is jammed - is this likely? Or is it something else?

Re: Wash motor does not run: Inlet/Drain error

Wordhog: Does sound like a siezed wash pump to me. Wash motor needs to run to get the correct level of water.

To drain a Miele dishwasher, start the machine on a cycle. All the Miele range of dishwashers drain before filling. Then hold in the start button until the end/finish light is lit. Keep doing this until all the water has gone. You could just get a jug and bail it out. Once the jug does not do the job anymore, switch to a cup, I use a very large syringe for the remaining half a litre.

Pumps water in don't wash and pumps out again

Not sure whether a schematic will help unless you have some understanding of the location of the components. It would help if you are able to clarify what you mean by pumping in. Usually you should hear the water inlet valve turn on to let water in. Then the wash motor should run to churn the water around and then the drain pump should drain the water out. What is happening is the dishwasher is leaking water as soon as it fills. This causes the flood switch to turn on and that triggers the drain pump to empty the water. Usually Bosch dishwasher have an inline water leakage detector. Check under the sink where water inlet tap is located. There is a device connected through which the water get in. The hose is detecting leakage. Need actual model number of the dishwasher to investigate.

I have a year old kitchen aid dishwasher and during fill cycle it makes a thumping noise. The dishwasher every 5 or 10 seconds shuts off fill cycle then turns back on which I think is what's causing...

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Enter your model number to see parts for your dishwasher.
Help me find my model number

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Enter your model number to see parts for your dishwasher.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Enter your model number to see parts for your dishwasher.
Help me find my model number

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Enter your model number to see parts for your dishwasher.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Our fisher and paykel dishdrawer won't wash. It comes up with F1 and flashing light on control panel.

the dynamo dishwashing stuff has caused foaming which reached the base of the dishdrawer unit causing the flood switch to trip. This gives F1 error.
Not sure how much foaming has occured.

Best to turn off power and take power cable out from socket. then empty the drawer using towels. pull out the bottom drawer and wait a day or so to let the foam disappear from the bottom of dishwasher (under the bottom drawer). Connect the power and see if F1 had gone. If not, you need more work. Post a comment based on the above suggestion and I will guide you further if required. Always use Finish dishwasher power only (recommended quantity) as the drawers are small and don't need much detergent.

Miele dishwasher Model G1023 drain light stays on and dishwsher will not work

Hello fellow DIY'ers,
Have just had the red light drain/inlet error terror!
Tried all the basics, including:
- check and clean inlet hose filter,
- check and clean drain hose,
- remove and clean all the filters in the bottom, and
-remove and clean the non-return valve.
Still was left with water in the bottom at the end of the wash and the red light drain/inlet error.
After researching further I found that this light also indicates a flooded unit. There in a shallow pan in the base plate and if water collects there it activates a float switch, stops the wash, and lights up the drain/inlet error.

To fix it:
- Disconnect power, water and drainage.
- Pull out your dishwasher, suction/remove all the water from the bottom. This includes the water in the salt reservoir, the drain pump and non-return valve.
- Tip the dishwasher onto its back.
- Remove the four star head screws (sometimes a small flat blade screwdriver will fit these) from the base plate.
- Remove and inspect the base plate. It won't have any water in it as you've just tipped it up. But you will see if it's wet and any staining where the water has sat. It only takes a small amount of water to activate the switch.
- Clean and dry the base plate.
- Have a good look around for leaks in the base of the unit. There was none in mine. Our dishwasher is a snug fit under the bench and we had been doing 2-3 washes per day for several humid weeks leading up to this problem. I believe the water builds up over time and doesn't get a chance to evaporate.
- Put it all back together again and test it.
- If it works, go buy yourself/your family dinner because you just saved yourself about $420!

No water is coming in the dishwasher. I can hear the water running, but the water is not coming into the dishwasher

If you can hear the water running - but it's not filling, you most likely have a drain problem, which is being stuck open. Usually the motor kicks in and either pumps the water through the wash arms (during wash cycle) or through the drain (during drain cycle) the switch that/or flap could be stuck on the drain and it is pumping it out the drain all the time instead of the wash arms.

The 4th green light on my Ariston dishwasher flashes. What does this mean?

You did not mention what model number that you had but this is what I found after a little digging:

From :
For future reference, the technician who replaced the control board for me gave me a complete list of flashing LED fault codes for the Ariston LL65 (which are same as Ariston LL64):

001000 Float Switch: Water in Base Pan
001100 No Drain: Dranin Motor Disabled, Filters Clogged, Dramin Hose Blocked
001010 Main Motor Presure Switch Blocked Filter
100100 Control Board: Software of Control Board not Recognized.
000100 Water Valve: Water Valve Diabled <--- This one sounds like your error
000110 Fill Fault: Water Valve Disabled, Turbine Disabled or Control Board
000101 Heating Element disabled or High Limit Open or Control Board
000010 NTC defective or not positioned or control board
000001 NTC defective or not positioned or control board

KEY: 0 = LED off
1 = LED flashing

I also found this for a different model:
No Program Code Fault condition
1 Heavy wash 1000 Operation of flood
protection system
2 Normal wash 0100 Heating
element/Thermistor/Thermostat fault
3 Rapid wash 0010 Drain pump fault or drain
4 Soak wash 0001 Not filling to correct
level within 6 minutes

Fills, doesn't pump to sprayer, drains on drain only cycle

Sounds like there is still something in the pump. I am 99% certain this unit has a reversable motor.

Dishwasher won't fill

could be. there is a float in the base of the machine. take the bottom front cover off and have a look. alternatively, tilt machine over and see if water runs out. water in the base of the machine means you have a leak
