Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4

Observation:

Check condensate trap for blockages or restrictions.
Note:
1. The bottom of the condensate trap can be removed without the need to remove the trap from the appliance if the appliance is installed correctly. This is achieved by turning the clear section of the siphon a quarter turn anticlockwise and then pulling it downwards.
2. Before reassembly check the integrity of all disturbed gaskets and seals and replace as necessary.
