Mira Sport Air Boost 10.8A - Power but no water

[Al@n]

Hi,

Shower stopped mid-cycle and now fails to pass any water through the system, I have checked the water filter, checked the PCB cable is on secure, but nothing.

All lights show correctly, and it sounds as if it is trying to pump the water, but not even a drop comes out; regardless on temperate / power setting. Shower is approx 3 years old

Test the solenoid, resistance should be around 4.9 ohms.
Apologies for the typo meant to type 3.9.
Thanks to Johntheo5 for the correction.

If the solenoid is fine, what else could it be? Anything else I could test?

Possible PCB faulty

Great, I'll test the solenoid, is there anyway to test the PCB?

If there is ,you would need to be fully versed in electronics ,but I am not unfortunately.

No worries, thanks, I'll test the solenoid, I hope that's the culprit. Will report back

4.9K ohms maybe?, my Triton solenoid resistance is ~ 3.6K ohms.
