Been out to this twice checked it out but could not find a fault have stripped it down looked for blockage but tank is filling fine changed stats, customer still says not drying what have I missed?
The little green fan belt on the back- is it worn and stretched? Was it off when you dismantled it? Change it in either case. Both cause a loss of volume of air over the heater; ie stats switch on / off regularly = very low heat in the drum. Also, make sure the belt is refitted in a ‘figure 8’ shape. (there’s a diagram of this on the back of the plastic cover plate). If it’s fitted in an ‘oval’ shape it will run the fan in reverse giving the same result as a slack belt – low air volume. Check the felt guide is in place under the green fan belt to stop the belt from fouling on itself where it crosses over ( figure 8 )
Don’t forget the condenser – could be blocked as well. 😉
