Paloma Water Heater

[Traveller]

Whilst working ok the Water Temp Control Knob has seized and I cannot therefore turn up or down the water temperature. Can anybody offer any pointers on how to fix this or is it Paloma are out of production so get a newer model :-(

[Paloma Bob]

Hi there,

Which model Paloma do you have ?

 

Regards Bob

PH5-3F, I believe but I am not on the boat at the mo. The pic I found on Google looks identical though.

It seems to be lack of use as a temperature adjuster which causes this - mine has done it a few times over the years -

my solution - remove the control knobs and cover and then using a small adjustable spanner or pliers on the shaft

gently work the adjuster back and forth until it is all free, dont use the knob - it doesn't feel strong enough. I have

done this at least 4 times over the past 10-12 years (usually when re-commisioning after the winter draindown)

and it has always worked ok.

 

maybe a monthly adjustment to the temp control would prevent this ?

Thanks Springy, sounds like a plan to me :-)

I spend half my life freeing these of, as Springy says, "that's the way to do it".

Thirded!

Also, Can I just add that Paloma Bob is a valuable resource for Paloma owning boaters. I have one of his recons and the service was amazing. Cracking stuff!

[Traveller]

Thanks everybody for your input. I will certainly remember Paloma Bill and the service he provides.

Try what has already been suggested and if that fails, or you wring off the shaft then get back to me and I'll tell you what you can try next.

P.S. I spend all my life freeing these :-(

And if Paloma Bill lets you down, try Paloma Bob!!

glad you have £125 lying around to blow ;-)

[Traveller]

Tried easing with a a grip (after removing plastic knob) but it really is locked solid and I could not get it to move :-(

 

Any further suggestions?

Give Bob a shout

[J R ALSOP]

Try harder.

[Traveller]

Got as far as using mole grips - if I'd tried any harder the heater would have come of the wall or the spindle would have snapped. I'll drop a pm to Paloma Bob.

Its just that fine balance between freeing it and breaking it - I tried to move mine yesterday - its stuck !!

Freeing siezed valves and screws is a fine art. Brute force and ignorance may succeed but a little finesse and patience will provide a permanent repair.

 

Aternately apply gentle tightening and loosening pressure. There may initially be no perceptible movement.

 

Gas taps can usually be dismantled, cleaned (maybe lapped in) and lubricated with a suitable grease.

An alternative approach is to remove the plate which holds the rotating part of the valve in place and then to pull the valve out, without twisting. You are much less likely to break the spindle when it is in tension as opposed to torsion. This has worked for me on a couple of occasions.

 

PS It is a good idea to drain the water heater before starting to do this!

Hi

 

I have a stuck temperature adjuster, tried WD-40, penetrating oil and heat and it will not free up.  I did manage to pull the splined shaft out of the valve.  Can the valve bodyt be tapped out?  Looking at the photo, the pencil is pushed into the inlet pipe as far as it can go. Is the pencil resting onto the rear face of the temperature adjuster valve or is touching up against  an internal wall in the valve?

 

Any help much appreciated.

Hi

 

I worked it out, and the shaft can be driven out with a drift replacing the pencil position. 

Happy to now have a cleaned and fully working temperature valve.
