My fisher and paykel smartdrive washing machine sensing balance error even when machine is empty, how do I fix it

- 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

change the board

Noisy
If the user is complaining about noise, it may be in a number of different areas. Is the noise during
spin? Is it a banging sound? This would typically be the drain hose, inlet hoses, mains lead or
harness. If it is an out of balance noise, check that the machine is level and stable. Check the
bias spring and balance rings. Remove the inner bowl and check that its weight is within
specification (Refer Section 1.12).
If it is a 'clunk' that occurs up to 3 times per cycle, this would be a bowl check and is completely
normal. It occurs when SmartDrive is draining and 3/4 empty. This is a 'feature' and a noise that
cannot be reduced.
Other things to check are:
• Is SmartDrive level and on all four feet equally.
• Check the mains lead, inlet hoses and drain hose outside the wrapper, behind SmartDrive.
• Check the harness and drain hose inside is not banging on the wrapper during spin.
• Check the bias spring is fitted correctly.
• Check the 2 balance rings in the inner bowl contain water. Check the bowl weight.
• Check for noisy suspension rods.

Hi Craig
Was the drum was banging with no load in it.
It can be two things suspension rods or the bowl is faulty.
All the water has leaked out of the ballast rings on the bowl,
causing it to go out of balance.

The error code is displayed when its beeping.
I don't know the error code, so It can only be three things,
Out of balance switch,Lid magnetic reed switch,Or Rotor position sensor,Your error code would help me work out witch one of these are faulty. to work out your error code look at picture below.
Add up the lights that are on.

Take a look at this document.

106. (01101010) Display Module to Motor Control Module Communications Error
These faults are reported when the Display Module detects an error in the communications
between the Display Module and the Motor Control Module.
Primary Source: Display Module.
Action: Replace Display Module.
Secondary Source: Motor Control Module.
Action: Replace Motor Control Module.

make sure yourhot and cold taps are on even when on a cold wash and see how you go

bad relay,pump contacts not closing

Fault is out of balance switch stuck on i removed and cleaned mine with crc but if still stuck on may need replacing hope this solves your problem
