I have a portable dehumidifier (Wickes own brand; I think it's a
compressor model?) about 18 months old which has stopped working.

The humidistat appears to be working in that if you turn it up, it
clicks in and the dehumidifer motor starts working; however the water
output container remains bone-dry.

Any thoughts as to what might be wrong, and whether it's repairable or a
bin job?

Thanks
David
