shower solenoid valve problem?
 

We have a Triton Ivory shower. It didn't work when switched on today.
Power and water seem OK.

Looking on http://www.showerdoc.co.uk/faq/electric.html it suggests that
it might be the solenoid valve that is faulty.

Looking on http://www.showerdoc.co.uk/faq/multi-meter.html it says that
if it is a good solenoid the resistance will be 3.4K Ohms or above. I
can't get any resistance reading, suggesting that the solenoid has
failed. Am I correct in this assumption?

Is the solenoid valve an easy part to fit? (I replaced the pressure
relief device about three months ago.)

It happens that Tom B formulated :
Looking on http://www.showerdoc.co.uk/faq/multi-meter.html it says that
if it is a good solenoid the resistance will be 3.4K Ohms or above.

Which is obviously wrong!

'....or above' could include infinite resistance, in other words an
open circuit - with no change in the meter display whether connected
across the solenoid or not. What should have been specified is a range
of reading (min and max) which should be assumed to mean the solenoid
is probably OK.

I
can't get any resistance reading, suggesting that the solenoid has
failed.

If the meter indicates no change between connected directly across the
solenoids terminals and not connected across it, then you can safely
assume the solenoid is faulty. Check the meter in not on 'Hold' and
that the resistance range setting is also correct.

Interesting.
