I hope that I can help you . You say that the pump isn't running at all. Have you checked any circuit breaker or other at the consumer unit.
Would you be competent in testing whether there is power to the pump. If not I would advise for safety that it may be prudent to contact a competent electrician.
It may be just something simple like a fuse or a trip out. Is there a fused spur outlet that the pump is connected to? If so have you changed the fuse.
Is it possible to plug in a small lamp to see if there is power to the socket?
Ok thank you . If you now put the pump plug back in what happens now? also the pump my be stuck can you give it a tap with something wooden, ( this sometimes works.as having done it myself)
If all this fails then I would suspect it is the pump itself that has gone faulty
From your shower do you have water coming out at all ?
Thanks for your reply , I am sorry but it seems that the pump itself has failed. It will probably need replacing. Can I ask how old it is?
For it to fail it may be older. If it is a rented property the landlord is responsible or if you purchased the property then I am sorry it would be best to get a plumber to change it for you.
I hope you get it sorted satisfactorily, As I feel the problem is the pump Then I cannot offer any further advice.
If you feel I have been of help, would you please rate my replies.
Thank you kind regards
