4.9Lid Switch and Out of Balance Switch

Lid Switch

If the lid is raised, the lid switch operates and stops the cycle when Smartdrive is stirring during fill or Smartdrive is spinning, (braking). The motor should stop within 10 seconds, all the energy from the motor is dumped into the brake resistor (Phase 1-4) or the pump (phase 5). It is important to understand that it can be a worthwhile test to open the lid at 1000 RPM, this will exercise the braking circuitry in the Motor Controller. If Smartdrive appears not to start it could be that the lid switch indicates that the lid is open.

•The user may lift the lid during agitate to add clothes or watch the wash action. However, the motor will stop if this is tried during spray rinse or final spin, or stop during fill.

•Smartdrive should pause when the lid is opened 50mm and restart at less than 12mm.

•Phase 1 and 2 (most) used a mechanical lid switch located on the Display Module.

•Phase 2 (Late) to 5 .The lid switch is controlled by a reed switch located under the top deck on the right hand side towards the front. The reed switch is activated by a magnet which is moulded into the lid assembly. This switch is closed when the lid is closed. Use a multimeter to check operation. The resistance should be less than 2 ohms. Ensure that the wiring to the reed switch does not get trapped in the top deck when reassembling.

•A ‘recently manufactured one piece lid’ is not designed for use with Phase 1 & 2 lid mechanical switches. There is a hole at the back which does not push the lid switch lever.

Out of Balance Switch

When the Smart Drive is spinning it can sense when the wash load is out of balance and will stop and retry spinning. If Smartdrive still senses an unbalanced load it will stop, give a short burst of beeps every five seconds and the RINSE or SPIN light will flash. The load must be redistributed more evenly . However, GW and MW models have the option where Smartdrive tries to automatically correct out of balance loads. If it detects an unbalanced load, it will fill with water and agitate to redistribute the load before trying to spin up again. Smartdrive has this option turned off to conserve water, it may be turned on in OPTION ADJUSTMENT MODE.

•This switch is normally closed, (phase 2-5) normally open, (Phase 1). Some Phase 1 Smartdrive were fitted with 3 terminal switches, make sure these are connected to the normally open position.

•Check operation using a multimeter. The resistance should be less than 2 ohms when closed.

•Fault code 43 indicates that this switch is permanently activated.

•Replace switch if there is any sign of corrosion.

•Phase 2. Technical bulletin WM70. Changing the OOB lever to an improved design can improve the operation of this switch.

Out of Balance and Lid Switch Test

The status of the switches may be monitored in Diagnostic

Mode. Diagnostic mode is accessed by pressing ‘Wash Temp

Down’ and ‘Power’ buttons together. See section 8.2.
