Triton T300si Solinoid valve not opening

Hi hope you can help. I am a plumber with quite a lot of electric shower experience but this has stumped me! I have fitted a new heat can due to lime scale blockages etc. Afterwards the shower would go through starting sequence but no water. Checked the PCB to find only slight reading at the P3 terminal feed for the valve. Spoke to Triton tech and they said it had to be a faulty PCB. So ordered & fitted new one but still the same problem Can you help Thanks

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
