Inlet/outlet light comes on

Started as a sporadic fault: stopped cycle after first pump in/out, then in/out light came on. Have checked the drain pump impellor as the manual suggests, but the machine has now stopped altogether. Nothing seems to be wrong/blocked with inlet or outlet pipes. Help?!

    I have experienced a similar fault. When initiating a wash cycle the machine will not start and the red inlet/outlet light comes on. I usually follow a set procedure as follows (But you can skip this lot and go straight to 'plan B' described at the end if you like.....).

    1. Firstly I switch off the electrical supply at the outlet then remove the filter and check the water level in the sump - usually the water level is too high and I use cups and a sponge to transfer water to a bucket until there is virtually no water left in the sump.

    2. While down there I flick over the metal retaining spring clip (it hinges over into the sump) then lift out the impeller cover and inspect each paddle and remove debris if there is any blockage.

    3. Refit the impeller housing by entering the outlet pipe first and pressing down firmly - clip the metal retaining spring over the top until secure.

    4. Clean and refit all the filters.

    5. I then inspect the outlet hose by releasing the connection to the outlet pipe - occassionally this can be slightly restricted or clogged but is often free running.

    6. I isolate the water inlet and unscrew the brass inlet connection (mine has a bulky unit that has a plastic cover and I suspect contains a device to detect inlet water flow). Upon inspection there is a small screen/filter and on some occasions this has appeared to be clogged up with hard water limescale deposits but is easily cleaned with a toothbrush.

    7. Reconnect brass inlet connection and open water isolation valve.

    8. Electrical power is reconnected and I try to initiate a wash cycle.

    9. If the red light for Inlet /outlet still comes on and the unit still won't work I then carry out plan B ...

    Plan B is really simple. Switch off the electrical supply, go and have a cup of tea. Return to the dishwasher and set the temp dial to 'STOP'. Reconnect the electrical supply, switch the unit to the ON position then press the start button and select a wash cycle. The inlet outlet light has gone out and the unit starts its wash cycle. Hey presto... Now why didn't I try plan B in the first place?

Machine is possibly not filling with correct amount of water if this light comes on early in the cycle

Have a bosh classixx 6 1200 started to work and now has f21 flashing at me not sure what it means and what to do


It is possible that the machine does not start off the cycle because there are errors due to feedback from the inputs. For the program to start up the main program controller must initiate the INLET/MOTOR/DRAIN pump/ valve to open up and allow each function to be driven starting from the flow of water into the drum as also the drain valve to open to exit the water at the point of the program cycle. If this does not happen then the voltage at the valve/motor/pump must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. Once the water comes into the system the WATER LEVEL SENSOR - normally a pressure switch- must activate at the preset/chosen level to give the signal to the program controller to switch on the motor. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor for rinse and wash.

Check this link to replace the inlet valve:

http://www.espares.co.uk/advice/washing-machines/a/7/1408/how-to-replace-the-inlet-valve-on-a-washer-dr.html

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

No water entering machine. machine had stpped, as there was a piece of cling film blocking the outlet, this has since been removed but machine will not wash.

If the motor does not start even when the water level is reached and inlet valve cut off, then check the output to the motor, if absent the controller is faulty if not check on the motor, motor capacitor, belt.

It is possible that the machine does not start off the cycle because there are errors or back feedback from the inputs. For the program to start up the main program controller must initiate the INLET valve to open up and allow water to flow into. If this does not happen then the voltage at the inlet valve must be checked or the fault relates to no voltage from the controller. This means the controller is a suspect.

Machine gets to spin cycle, stops, and displays Error code 20.


Program does not move on as there is data error on the spin cycle due to wrong commands from the water level sensor/ program drive.
You must see if by choosing another program the fault changes, if so the drain valve or pump is faulty.
Check for dirt in the inlet, outlet valves, clean and set.Check the water level sensor.
This must clear the issue.

Inlet/outlet light keeps flashing on G641 dishwasher - have checked filter and cleared debris. Just completed a wash but dishes not washed or rinsed adequately. Anything else I can check before requesting...


hi,

this is a general fault light which could mean anything without a Miele Technician coming out and connecting a
laptop to the unit. However most common faults with dishwashers is a drain fault. Check for any kinked hoses and check the drain spigot under the sink where the drain hose connects into the u bend. Usually this is where food gets trapped due to the spigot not being drilled out large enough. This then causes a blockage. Also check the non return valve under the filter and make sure the drain pump can turn freely. See what part of the cycle the unit lights up the fault. If it happens at the very start it is the drain. If it drains ok then fails it is the inlet. If it fails after that it could be any number of things.
Hope this helps.

Miele G638 dishwasher.


Hi John I have the same problem, the manual says that it is because the water level is to low, this is checked by opening the door after the machine has stopped filling and before it starts to wash, the level should be 4mm above the main plastic filter ring, the level has two settings, these can be adjusted by pressing the start button and the On/Off button at the same time, release the start button and turn the control to economy 45,if the start light does not come on the level is set to normal, to increase level press the start button again and the light should come on, this will give you an increased filling time. it did no help me but it may help you. good luck
