What it is

Signs this part needs replacing
- The appliance is completely dead, with no display or indicator activity at the control box.
- Controls or settings are unresponsive, or the unit will not accept commands.
- Fault codes relating to the control or internal wiring persist after resetting.
- Intermittent operation, with the appliance cutting out or restarting without input.
- Visible damage, scorching, corrosion or moisture inside the control box enclosure.
Before you order
- Confirm the appliance model and variant from the data badge, as the VWL 45/1, 65/1 and 75/1 share this control box but other variants may not.
- Check the existing control box part number against 0020146806 before ordering.
- Isolate the electrical supply and verify the fault is within the control box rather than the appliance wiring or external controls.
- Confirm whether the fault lies with the control box assembly or a separate component before replacing the complete unit.
