Water in electric shower just stopped

[endecotp]

Yes that appears to be a failed solenoid, should be around 4kohm.

No! Look at his picture! He has just put both probes on the chunk of metal that holds the solenoid in place!

@Keitai, seriously, be very cautious about what you do here. There is mains electricity and potentially very high currents.

How old is the shower? You still have the guarantee sticker on it, it is still covered?

Think 2 years has expired. The electric is isolated when I tested for resistance.

Normal coil resistance should be ~ 3.0K to 3.5K.okms, 3000/3500 ohms), Set the resistance scale to 20K and see do youget a steany resistance reading of 3.0 to 3.5 ish, it will not read the correct resistance even on a "good" coil if set to the 200K, I have a old Triton coil in my box and it reads 3.75 on the 20K scale but on the 200K scale jumps around a bit and then reads _1 which is meaningless really.

Ok will do, as someone pointed out the probes are just on outside metal of solenoid, I'll put them on the terminals

Do you think he will understand any of that?

I understand put multimeter on right setting.

The electric is isolated when I tested for resistance.

But not when you were using one hand to hold two probes on the live mains terminal and also hold the meter, and using the other hand to hold your phone!

Please do me a favour and keep posting regularly so I know you are not dead. (That's not a joke.)

Is this your shower, or is it someone else's and you are pretending to be an electrician?

Oops, well spotted. Should have looked better, possibly is still the solenoid though.

Remove the coil plug with the blue&black wire, and test the resistance in the coil.

 

[HERTS P&D]

Move away from the shower, do not go near the shower, CALL SOMEONE WHO KNOWS WHAT THEY ARE DOING!

Remember you had a thread asking what size screws to use for a wall bracket!

Remove the coil plug with the blue&black wire, and test the resistance in the coil.

Isolated the unit and pulled out the blue and black wire then put the two probes into both where the the wires are and where they came out- nothing (no reading). Have the probes been put in the right place? I'll order new solenoid from mira I guess. Meter set to 20k ohms.

Which photo goes with which?

You mean meter reading? It showed that permanent 1 when I put the probes in both places. It didn't show anything except one the whole time.

Order new solenoid?

At this point, I would (1) make sure you're making contact with the pins correctly, (2) try on a higher range, and then (3) dismantle the shower to extract the solenoid. It may or may not be easiest to remove the whole thing from the wall. Whether you want to do that is another matter.

Well it's gotta come off whether I replace it completely or change the solenoid over, surely? I'll unscrew three wires circled when I've got either solenoid or new shower
