MCZ Pellet central heating system

[Rob Foster]

If it’s stuffed spray it
Chk....thinking check all fuses etc

So if I'm not getting any lights, even when the system should be working and I'm pressing the grey arrow button then its probably an electrical issue to the pumps?

Yea sparky who knows heating systems should be able to help

Post no. 8 you said when you set them (valves?) to on, the pump light came on?

Did you hear or feel water move around the pipework?

To latch the valve in manual, push the lever across to on, then push it down into the wider part of the slot that's got the tooth like part on it.
Hold there for a second, as the spring tries to reset the valve it should latch on. (to release push lever up to the longer part of the slot.)
Does the pump stay on?

A heating engineer that knows heating should also be able to help you.

Yeah I saw that the lights came on for an unknown reason earlier in the day, but haven't been able to get them to replicate that since.

 

[Harvest Fields]

You might have tried his already but turn the heating Sam and off and that lever should spring back. Pull the lever fast towards you and see if the pump

I may know a guy if you get stuck

Ok ,then see if there is a manual override to th three way
Unit, you could try setting it to change back and forth, and I would give it a sharp smack with a wrench , it is probably stuck Chking
And give it a dose of wd40 plenty right down he holes by the lever,
Plenty mind you, let it penetrate for an hour or so smack it again,
Then see what happens , let me know Centralheatking

You are kidding right?

I take it you know this guy well and are kidding him along? Well I bl00dy hope you are.

Let's just spray a petroleum based fluid into where a freakin electric motor using brushes sits ! Sorry, but what the hell are you thinking Rob? At the very least, WD40 will start attacking the plastic gears. At worst you start a small fire...

Sorry, but that's just bl00dy irresponsible.

The unit is probably stuffed anyway so a squirt will not make things any worse , that’s my opinion and what I would do if it was my gaff....centralheatking

I didn't end up spraying them - took the covers off and watched them as they switched on/off - both two way valves are working fine by the look of them.

The only thing I cant work out is why the pumps aren't pushing water around. As I said earlier they did light up - but haven't done since. I've been around the place, set the thermostats up/made sure that every switch I can find is set to on - made sure that the return valve on the heating loop is open etc etc.

Completely stumped.

I would not spray any liquid onto anything that has 240v going to it but that’s my opinion.

 

[ShaunCorbs]

Can you see the micro switches working in them ?

Ok , we all need to fault find on his one, r u sure the pumps are actually pumping , often when they are bust,seized the impellor head will rotate but no liquid wil be moved , sorry about underlines I do not know how to switch them off

Chk

I would and have done and am living proof , but yes for amatures is probably not a best thing to do..my approach is often radical
But can work

Don’t care if your a pro or not. Still shouldn’t spray stuff that you actually cannot see.

Is there voltage to the pump? When the valves have motored?
