BAXI Luna 3 - no hot water

[geofear]

Part no 624

Many thanks Shawn, but 624 is the Rilevator itself. I have already replaced it. But if it 'works' with the "transducer", I think we're making progress here. And I see it has a plastic screen at its base.... Perhaps it is just CLOGGED and can be cleaned?

I could almost guarantee its the Transducer.
The part that the rilevator fits onto.

Baxi part no: JJJ000620340.

Patience is required removing the part.
Difficult to get a socket onto. Can't really do it with a spanner.
The faint red light on the rilevator may not sense enough flow for the unit to fire up on DHW demand

OZ, are you in Britain?

Is it making a solid red light when waters flowing ?

Also if you live in a hard water area then yes I would clean the screen

I think imo it’s flickering?

In your experience, when DHW demand, does the Rilevator show a constant red light, NOT FLICKERING?

Yes should be constant sounds like the flow sensor is getting old part no 81

No Shawn, NOT solid at all.... rapid flickers. SHOULD it be solid?

Yes should be constant sounds like the flow sensor is getting old part no 81

Obviously have to turn off the incoming water. But will it back-siphon all the hot water from the lines above this level?

Easy way to test pop the sensor off keep the wires on / attached and get a magnetic screwdriver and rotate / spin the screwdriver around in the hex bit in a circle motion this will fire the boiler up for hot water so have a tap open after you popped the sensor off

The red light should be constant

To clarify, to test the transducer, rotate a magnetic screwdriver in the rilevator?

 

[ShaunCorbs]

Yes In the part 624 spin a magnetic screwdriver in a circular motion eg move it around in the hex clip

No, I'm not.
I reside in one of the Colony's.

There is a plastic strainer at the bottom of this part and also a wire mesh strainer inside the part.

Just replace the whole part, they do a lot of work and if you get more than 4 years out of them you're doing well.
I always have 2 or 3 of them on hand due to necessity.
