Electric shower cutting out - Salamander CT50 Twin (2014)

[HokkaHokka]

Hi,

I hope this is the right place to post this, but yesterday our shower developed a fault and the power would not kick in.
I switched it off at the power and ran the water for a bit which seemed to resolve it but we had the same problem today but worse. I managed to get it started again but it only goes intermittently and keeps stopping after about 5 seconds of flow before starting again then cutting out etc.
Any advise please? I'm wondering if the pump has had it or there is not enough water going through?
We have a tank in the loft and cylinder in the upstairs airing cupboard beside the bathroom.

Thanks

HH

1. Check the electrical connections, provided you feel confident in doing so.
2. Isolate the water and check and if necessary clean the inlet filters.
3. If not one of the above, possibly a flow switch issue or air in the system.

I’m slightly confused, is this an electric shower fed by a pump, Or is it a thermostatic shower fed by a pump? Is it just the shower that’s affected?

Thanks for your help. I'm not tech savvy (to my shame) & I'm assuming the electrical connections are more than just the plugs that go into the wall. Would this be straightforward with the power turned off? When you say isolate the water, do you mean turn it off at the cylinder and the mains? Are the inlet filters easy to locate and clean?
If it does turn out to be a flow switch issue or air in the system do you think I would need a professional to inspect and would it be best to go with an electrician or a plumber please? Thanks again and again sorry for my lack of knowledge.

Thanks for your reply, I'm not completely sure what the difference is. As it is connected to the cylinder in the airing cupboard would this suggest it is thermostatic?

If the shower is fed from the cylinder and the cold tank, then yes generally thermostatic. If you pull a cord in the bathroom and have a cold mains feed then generally an electric shower. The electric shower uses electricity, and heat up the cold water coming in using an element (like a kettle or immersion heater). A thermostatic mixer shower blends the hot and cold water from a heated source, like a cold tank and cylinder, combi boiler etc.

It's definitely thermostatic then. Thanks for helping me understand the difference.
Have you any experience with this issue and what level of expertise would be required to resolve?
As mentioned, running the tap with the power off helped temporarily but it is worse today. Is there anything else you would suggest trying?
I'm hoping that it won't be too costly to rectify...

Thanks, followed the advice for air in the system but still no joy unfortunately

Is it just the shower suffering, or any other outlets connected to the tank?

Hi thanks - just seems to be the shower that is suffering.

You should have valves on the inlets, if not someone needs a kick up the rear, and you will need to drain the cold water storage tank.

Thanks again for your help.
I have been able to turn valves to cut off water supply and disconnect the inlet hoses from the cold water tank and the hot water cylinder, but only the cold water hose had a filter - is this normal?
There was a little debris on the single filter that I found which I washed off but it hasn't corrected the problem unfortunately.
I assume that I don't need to check outlets for filters (i.e. pipes leading from the pump to the shower) or should I check these as well?
Thanks HH

Both hot and cold should have filters. See if someone has fitted the hot one on the outlet.

Thanks - If it is on the outlet, should it be moved to the inlet?
Might it make a difference at this stage? I've not had an issue in the six years that I have lived in my current home.
