OK thanks for that I have done as you suggest but the clicking continues from the back. It is coming from the water inlet at the bottom right hand corner, when viewed from the rear. Is it ok to run the unit with this??
OK done that, the noise is coming from the blue component where the water enters the unit(inlet valve) It sounds like a relay clicking and is intermittent. Sometimes quiet for a minute or so then maybe a single click or several.
OK done and clicking has stopped, the compressor came on for a few secs and then stopped. I reconnected the wires and tried again, clicking back and compressor did the same. So I have again disconnected wires and will see what happens.
Ok thanks. compressor now running as normal, Thanks for the help, job done. Ta very much,
