Hi, I have a similar problem with my unidare WMS712N.
I have carried out the suggest made by a user on this website, when opening up the storage heater I could see a red light which i could push?
Ive had two call outs and both times they can not work out the problem.
In total I have 4 storage heater and only one of them work one call out suggested no power going from the mains to the heater (run on different fuse boxes) if this is the case then why is one of them still working?
I believe where ive cover the heaters from time to time ive over heated them.
Please can someone help!! any suggestion would be great. Thanks
a very cold person!
