Mira sport Airboost fault

[Robertspaw]

I have a Mira sport Airboost shower. The unit is turning on but no waters coming out and the light on the low power button is just flashing…

Any ideas?

Thanks

Sounds like the solenoid has failed. Do you have a multimeter?

 

[Robertspaw]

Yes have a multimeter but not got a clue what to do with it

Measure the resistance across the two terminals of the solenoid ,disconnect one of the cables going to it ,after you isolate the electric supply to the shower, before taking the reading. Tell us what the reading is.
If you don't know what setting to use on the multimeter ,show us a pic of it ,and we can advise you.

As per Terry, measure the resistance measured in ohms

Ω this symbol, sorry, the site wouldn’t let me edit previous post.

Getting a reading of 3.5 on the solenoid so guess it’s not that?

It doesn’t appear to be. Next try the thermal cut out (tco), it’s a simple continuity check (that’s the one that looks like a wi-fi signal, or a speaker volume.

Tco seems ok - continuity setting makes beeping sound at least…
