This question is regarding Redring Expressions 500 8.5kw White (53553001 / 53553015) - Shower Spares

switching on/off

My shower switches on and off erratically but if you switch to medium the switching gets less and eventually stops. Then if you leave it a few minutes and switch to hot it will start switching on/off again and eventually the switching will he less and eventually stop. I have replaced the start/stop relay and this has made no difference. I do not get a overheat light when it is switching so I assume that rules out the to?

I presume you mean that the water stops flowing?

If it does then I think you have a faulty solenoid.


It may be your solenoid valve, you can check it if you have a multi meter, you should have a reading of at least k3.5 ohms, across the two terminals any less and you need a new valve. (Check the valve in the failed state.) (When it has stopped working!)

If there is power getting to the solenoid and it is not operating then there is a good chance that you have a faulty solenoid.

The video is intended as a guide and does not cover every shower.

If you don’t have a multimeter we sell them with a guide on how to use them for checking and testing the various parts of your shower.

Apart from helping to fix your shower, they are really useful for checking you have a power supply to appliances, for checking fuses and letting you know much power you have left in batteries

(So you will know if they are good or not) and lots of other jobs, in short they are well worth a few pounds
