Asko 1875 had a new main board, wax motor and temp thermistor fitted 6 months ago. now thw machine pumps in the water but does not wash what could be the problem

I am in Australia so my comment relates to that OZ power supply. The first thing I’d do would be to check the pump to eliminate it as the problem. To do that I’d disconnect at the supply end of the pump’s electric cable and make up a 3 pin plug patch lead and supply power to the pump directly through an RCD protected outlet, and see if the pump works independently of the control board. That would confirm the pump is ok and not going to earth (which would trip the RCD.)
Do the water inlet solenoids come off that board? Because if they are, and are mains voltage, check them the same way. Check everything that comes off that board at the appropriate voltage independently.
There will be temp and water flow and drum-wobble sensors which will be low voltage and all need to be independently checked at the right voltage for each to eliminate them as the problem.
A digital multimeter checking the sensors probably won’t do any damage (blow them up).
Visually check the board visually for any burnt or blown components. Some boards have a thermal fuse in the circuit.
Asko should be able to supply the circuit for the board and it’s values. NZ Govt has legislation that compels Asko to provide this info. We got a new board from Asko NZ by post.

Oh boy I hope you're in the UK cuz that is a British unit here are the error code explanations
Error 1
Washing machine door lock has failed to operate or respond
The washing machine has detected an error with the door safety lock or interlock preventing operation.
Check door is closed and latched correctly

Check door lock
Error 2
Water drain time out or failure
The washing machine has failed to drain the water in a reasonable time, nominally in six minutes.
Check that filter is not blocked or obstructed
Check drain hose is clear of any blockage or obstruction
Check wiring to drain pump
Check drain pump is not defective
Check level sensor or switch
Check wiring to level sensor
Error 3
Not drained in time allowed - washing machine fails to drain water
Check that filter is not blocked or obstructed
Check drain hose is clear of any blockage or obstruction
Check wiring to drain pump
Check drain pump is not defective
Check level sensor or switch
Check wiring to level sensor
Error 4
Washing machine has detected problem with the wash heater
For this error code you need to check both the water heater or element and thermistor, the washing machine is reporting a fault on the heating circuit with this fault code but it is not capable of identifying exactly where the fault actually lies.
Check water heating element
Check heater for contunuity
Check thermistor or temperature sensor
Check the thermistor resistance
Check wiring to water heating element
Check connections to water heating element and temperature sensor
Error 5
Not drained in time allowed - washing machine fails to drain water
Check water supply is on, clear and not frozen
Check the air chamber and pressure sensor hose for blockages
Check water inlet valve
Check wiring to water inlet valve
Check connections to water inlet valve
Check the main control PCB
Error 6
Motor heat protector error or failure
The washing machine has detected an error on the washing machine's main drive motor circuit in relation to teh overheat protector within the motor itself.
Check motor connector block
Check motor carbon brushes where fitted
Check wiring
Check tacho connections
Check motor
Error 7
Motor error or failure
The washing machine has detected an error on the washing machine's main drive motor circuit but, like other errors cannot pimpoint he exact location or nature of the fault.
Check motor connector block
Check motor carbon brushes where fitted
Check wiring
Check tacho connections
Check motor
Error 8
Washing machine has detected an overfill situation
This error code can be caused by overfoaming which is a result of overloading (see this article) or by overdosing or, incorrect detergent as the pressure sensor will falsely read that there is too much water in the washing machine.
Also check the pressure sensor and that the machine has not actually overfilled with water.
Check for overfoaming or over soaping
Check the air chamber and the pressure switch hose
Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller
UNb
Washing machine has detected an out of balance situation
This error code is caused by an imbalanced of incorrect load in the washing machine
Check for overfoaming or over soaping
Check the air chamber and the pressure switch hose
Check water level sensor
Check wiring to water pressure sensor
Check connections to water level sensor
Check main electronic controller

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive 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. 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. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.

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

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.

Hi,

Problems with a washing machine not spinning or not draining are often interrelated..

If you are having a problem with your top load washer then check out thistip...

Washing Machine does not Pump or Spin


If you are having problems with your front load washing machine then checkoutthis tip...

Hello, welcome to Fixya.

The "F4" code on those Asko washer`s indicates a fault has been detected with the thermistor.

This of course does not mean the thermistor is indeed faulty, it may have just become loose from the bottom of the tub.

Here`s what to look for and what it does...

THERMISTOR
Part no. : 80 616 63
Resistance: 40-60K ohms
Room temperature: 68°–86° F (20–30° C)

The thermistor ( for temperature measurement ) is
located between the motor cradle and the holder.

The thermistor measures and controls the water temperature via a heating element. In the event of errors the heater is switched out if the thermistor short-circuits or is disconnected from the program control board or programmer.

**unplug the unit from the dryer or wall whichever applies to your situation...safety first**

If you are capable remove the rear panel and top panel to ohm out the thermistor to varify if it is within` the values I provided...or perhaps it has dislodged from it`s position...though that is unlikely, it could happen.

In the event you need a thermistor and you feel you can replace it yourself I`ll show you how...I do recommend calling in an authorized Asko service provider.

CHANGING THE THERMISTOR

1. Remove the top cover
2. Remove the rear panel
3. Remove the thermistor by pulling it out to the left.
4. Remove the thermistor header connector from the program control board.
5. Install the new thermistor by threading it through the hole between the cradle and holder.
6. Connect the thermistor to the program control board.
7. Replace the rear panel.
8. Replace the top cover. (Don't forget the two
star washers for the outer screws.)


Hope this helps move you forward or at least gives you an idea of what needs to be looked at.

Let me know if you require further assistance. Thanks for choosing FixYa today.

Good luck.

may be carbons in motor and or board

Clean armature and replace brushes. When you remove the brushes the shut a small pin like device maybe protruding from the brush tip. this is a sure clue.

OK, just had the same problem wit my dishwasher, ASKO 1875, ,,,,,, Firstly, open the door and remove the tilt screws that secure it from tilting, top left and right corners at the front , pull the dishwasher out from under the bench enough so you can get to the back of the unit. Take care with the power cord [ should be turned off at the wall] . At the fear there is a panel at the bottom held on with 4 selftapping screws, remove these and ease panel away from the machine enough so you can see inside. Now you are likely to see alot of water sitting in the bottom tray, [ l did on mine } This exess water activates a small float under the pump which in my case caused the problem. Sponge the exess water out into a bucket, there will be quite a lot. Once dry try turning your dishwasher back on and hey presto the lights on the controll panel should be back to normal. Turn power off again, replace bottom panel to the back of the machine. Reinstall back under the bench, not forgetting to replace the tilt screws and all should work well....... Hope this helps. If still a problem you may have to dig into your wallet and call a serviceman. P.S. If you dont want to remove the back panel and sponge the water out, you can just tilt the dishwasher over to drain the water but this will cause abit of a mess {water } on the floor, but it is alot faster. Good luck.

The only other thing that could cause the ON light to turn off as soon as the motor is about to start would be a bad or loose connection that causes a break in the circuit. Even if the components are O.K. the connection could still be causing the problem.

Replace both the main control board and the wax motor. This sounds like a computer chip malfunction

As far as the squeak, make sure it is not the bearing located at the back of the tub under the large pulley.
