T80si not working after being unused

    Evening all,

    I've a T80si mains fed shower upstairs that stopped being used as the trap started leaking. We just used the other downstairs T90. It could be 2 years since it was last used.

    I got the trap sorted and have tried to get the shower working again but when I turn it on (heating off, flow high) there's a bit of buzzing for about 10 seconds but no water.

    I have verified power going to the solenoid and measured the resistance at 3.7k ohms which I believe to be correct but I suspect this is the issue.

    I'm wondering is the buzzing a good sign and maybe the solenoid is just stuck after not being used and may free up? It doesn't look like it's working trying to fix and I'd probably try get a tank fed shower in there instead if needed

    Any opinions?

    Isolate the power and water, remove the cover, remove the filter, check clean, crack open the water, when/if water starts flowing, re insert the filter.

    The buzzing is most likely the solenoid opening. It sounds like no water going to the shower. Possibly a valve turned off somewhere?

    It could be a blocked filter like John suggested but with mains water pressure I'd expect at least a trickle of water getting through a blocked filter

    Urgh, the bloody water was off. If you'd have asked I'd have said I didn't even know where the valve for it was but when I went looking I found it and it had been closed. Possibly by past me but I'd don't remember!

    Sorted now anyway thank you very much!
