Motor Controller does not work, how to remove the fault?

hi Pete, okay there can be one of two reason for that fault.

1. check the motor wiring from the controller to the motor and if possible check the resistance of the motor by checking the brushes, if you have a smart meter disconnect the motor wires from the controller and take a resistance reading we looking at around 0.3 to 1 ohms.

2. Controller fault , i can test the controller for you free of charge , you simply pay the return postage..

Regards
Rob.

E1
The flood sensor in the base has been activated for more than 20 seconds.

E2
The controller has not sensed the motor rotating.
Foreign object has jammed the rotor
• The rotor has failed
• hall sensor or wiring fault at the hall sensor or controller.
• The hall sensor has failed
• Motor stator winding or connection open circuit.
• The electronic controller has failed

You probably need to remove the drawer and check for signs of a leak to start with.

this could be a right brake fault or a controller fault. Check and see if the right motor has been disengaged. The easiest way to chreck this is to try and push on the right side of the chair. if the wheel begins to turn then the motor has been disengaged and you should be able to re-engage the motor and stop the wheel from turning. At this point you will have to turn off the chair and turn it back on to see if the fault goes away. If that is not the problem then it could be a loose motor connection. Check all your wiring connections on the motor to the controller. The other problem it could be is a controller fault. check all the connections on the controller and the wiring. Turn it off and back on to see if the fault goes away. If the fault is still there you will probably need to contact a service tech for them to get on line with the controller and find the root cause. They should have the diagnostic tools to check this.

Error Code 105
105. (01101001) Phase 2 to 5 - Comms. Error Time-out
These faults are reported when the Display module detects an error in the communications
between the Display module and the Motor Controller.
NB. If the product is an IW, check that the motor controller is not 426520. If it is replace with a
compatible part. This is incompatible and will give a fault code 105 at the start of agitate. Not
before! If it is a 426520 replace motor controller with a compatible part.
Primary Source - Display module
Action - Replace Display module.
Secondary Source - Motor Controller
Action - Replace Motor Controller
Tertiary Source - Rotor Position Sensor (Phase 5 Only)
Action - Replace Rotor Position Sensor. If the new Rotor Position Sensor corrects the fault refit
the original display module and motor controller.

The arm does not move as the program does not engage the WASH cycle and it seems that the program controller unit is a suspect. You can remove the connectors and connections to the controller after noting the details and reset, If the fault repeats then the controller is a suspect. Check motor free movement, check if motor hums, if so check and replace the motor capacitor.

81. - 95. (0101xxxx) Phase 2 to 3 - Display/ Motor Controller.
See fault code 106
104. (01101000) Phase 2 to 6 See fault code 106
106. (01101010) Phase 2 to 3 - Display to Motor Controller module
Communications Errors (Phase 6 IW also)
These faults are reported when the Display module detects an error in the
communications between the Display module and the Motor Controller module.
Primary Source: Display module.
Action:
Replace Display module.
Secondary Source: Motor Controller module.
Action:
Replace Motor Controller module. If the new Motor Controller module corrects the fault, refit the original Display module.

Possible that controller is faulty as there is no speed control. Check the switch and wiring to the motor. Sometimes it can be also the fault with the fan motor but can be confirmed only if it removed and tested with a bench supply.

A specific revolution is not detected from the main motor rotation detection
signal (MLOK*), causing the signal to go '1'. (main motor fault)
Possible cause .
The main motor (M101) is faulty. The controller PCB is faulty.
1) Connector
Is the connection of the connector (J903) of the main motor and the
connector (J06) on the DC controller PCB normal?
NO : Correct the connection.
2) Main motor (M101), DC controller PCB
Try replacing the main motor. Is the fault corrected?
YES : Replace the main motor.
NO : Check the wiring; if normal, replace the DC controller PCB.

fault code 136.

Motor Stall
The Motor Controller has been unable to start the motor. Possible causes of this fault are: Faulty motor harness, faulty or jammed motor, seized bearings or seals, faulty Motor Controller module, faulty Rotor Position Sensor or harness.
Check the motor harness, connectors and motor for discontinuity. Also check the Rotor Position Sensor and associated harness for water, mechanical damage or corrosion.
Finally Motor Controller module could be gone
