Replaced control 421306usp and valve 421177p in fisher and paykel wa37t26g, now beeps non-stop and fault codes...also can not turn power off at the machine

- Motor control module fault:
Fisher and Paykel washing machine error 1:
Primary Source: Motor control module.
Action: Replace motor control module.

3 - Motor control module fault:
Fisher and Paykel washing machine error 3:
Primary Source: Motor control module.
Action: Replace motor control module.

9 - Size setting fault:
Fisher and Paykel washing machine error 9:
Primary Source: Motor control module.
Action: Reset machine size as per service manual instructions. If fault repeats replace Motor control module.

10 - Temperature Sensor (Thermistor) Error:
Fisher and Paykel washing machine error 10:
Primary Source: Thermistor.
Action: Replace Thermistor.

11 - Pressure Sensor Fault:
Fisher and Paykel washing machine error 11:
Primary Source: Pressure Tube.
Action: 1 - Empty all water from the machine. Remove pressure tube from pressure sensor, clear pressure tube of any water and reconnect tube (blow down the tube is necessary). 2 - If fault repeats, replace Motor Control Module.

12 - Flood Protection Error:
Fisher and Paykel washing machine error 12:
Primary Source: Water Valves.
Action: If the water valves are on continuously, check that the water valves turn off mechanically by disconnecting power to the machine.
Secondary Source: Pump System.
Action: Check pump for blockage and drain hose for correct height(end not immersed in water) or kinked.
Tertiary Source: motor control module.
Action: If water valves are been driven on electrically, replace motor control module.

36 - Water Leak Fault:
Fisher and Paykel washing machine error 36:
Motor control module has needed to top up the water level more than 4 times during wash/rinse cycle. Most likely cause is waster siphoning out or the machine has developed a leak.
Primary Source: Drainage system.
Action: Check that the hose is not less than 850mm from the ground
Secondary Source: Pressure tube.
Action: Make sure the pressure tube is fitted correctly and doesnt have any holes.

37 - Blocked pump:
Fisher and Paykel washing machine error 37:
Primary Source: Drain System.
Action:
1. Check that the drain hose has not been kinked.
2. Check the length of the hose. 1m is maximum extension.
3. Check drain pump winding for open circuit.(Note: Pumps are fitted with a thermal cut out and will reset after cooling)
4. Check for physical blockage to pump and hoses.

38 - Pressure Sensor Fault(empty reading during wash cycle):
Fisher and Paykel washing machine error 38:
Primary Source: Pressure tube.
Action: Check if tube is fitted correctly, check for blockages or holes in the pressure tube.
Secondary Source: Motor Control Module
Action: Replace the module.

39 - Pressure Tube Fault:
Fisher and Paykel washing machine error 39:
Same as fault 38.

40 - Bowl Dis-engage Fault:
Fisher and Paykel washing machine error 40:
Primary Source: Mechanical.
Action:
1. Check that there are no clothes or other foreign objects preventing the clutch from re-engaging. Excessive suds can also stop the bowl rotating.
2. Check the clutch splines for physical damage.
3. Check that the pressure tube has not come off, kinked or blocked(blow down the tube.
Secondary Source: Motor Control Board.
Action: Change Board.

43 - Out Of Balance Switch Fault:
Fisher and Paykel washing machine error 43:
Motor control module has found that signal returning from the out of balance switch indicates that the switch is permanently on or the harness to it is disconnected.
Action:
1. Check the level of the machine.
2. Check wiring to the switch.
3. Check switch for continuity and corrosion.

44 - Water in Bowl During Spin:
Fisher and Paykel washing machine error 44:
Primary Source: Drain system.
Action: Check for blockages/kinks in drain hose and function of the drain pump.

48 - Hot and Cold Inlet Valve Incorrect Signal:
Fisher and Paykel washing machine error 48:
Primary Source: Wiring.
Action: Check the wiring.
Secondary Source: Inlet Valves.
Action: Check the resistance of the coils.
Tertiary Source: Motor Control Module.
Action: Change Module.

49 - Cold Water Inlet Valve Faulty:
Fisher and Paykel washing machine error 49:
Action: See fault 48.

50 - Hot Water Inlet Valve Faulty:
Fisher and Paykel washing machine error 50:
Action: See fault 48.

51 - Diverter Valve Fault:
Fisher and Paykel washing machine error 51:
Primary Source: Blocked diverter valve.
Action: Check for foreign objects in the valve.
Secondary Source: Motor Control Module & Diverter Valve
Action: Plug the machine into the power point but off at the control panel. Check voltage on the plugs at the diverter valve. If voltage around 230V, change diverter valve and motor control module

sounds like a valve fault. this fault can be caused by the electronic board not powering the valves also. check power to valves during fill, if power, replace valve. if no power replace board.

the motor controller needs replacing. this fault is not servicable at home.

the lights are a fault code, this will help with diagnosis. check your motor for corrosion.

This is error code 51
51. (00110011) Phase 5 and 6 Eco - Diverter Valve Fault
Primary: The motor controller has registered a drop in water level in the
recirculation phase of the wash cycle, water is being drained instead of recirculated.
Or water has been sprayed onto the Valve from an external source and caused the
solenoid to blow.
Action:
Turn the power off at the machine but leave the power on at the wall, then measure
the voltage across the terminals of the wax actuator, if a reading of 230V is
achieved the motor controller has failed due to the valve and both will need to be
replaced.
Secondary: Check for blockage in the valve itself or a broken hinge mechanism.

check motor brushes, or binding brake, centrifugal clutch Re: Jeff

Hi just read your posting.Now is your machine an Aqua smart model?Does the pump you touched have a fan attached to it?When the machine stops does it beep and show an error code?Problem could be the pump but please reply with answers to the questions and I am sure I can help you rectify this fault.Looking forward to your reply.

Fisher & Paykel Smart Drive beeps and stops during rinse cycle. If I hit pause and wait and restart it eventually continues. It seems like it has problems detecting water level.

Hi just read your posting.Error Code 49 means your Cold water valve is faulty,Or your control module is faulty.To test this fault you need an electrical test meter to test the water valve coil for conductivity.Have you or can you borrow a test meter to check the water valve?Please reply on how you would like to proceed and I am sure I can guide you throe the steps needed to rectify this fault.Looking forward to your reply.

Fault 49 usually points to the cold inlet valve. I have come across many with this fault that the valve tests ok and it needs the motor controller replaced.
