Worcester junior greenstar - overheating

[moony]

As title but of background

Called out to boiler seized pump, split seals and air vent spewing out gunk....

Changed pump and body....

Pump starts, fan starts, ignition sequence - fires.... Within seconds overheats and starts sizzling and banging in main heat ex....

Now this cust is skint I've helped her out by changing pump....

Dies the main heat ex block up on these ? Or any other ideas ?

 

[Aquazone]

You changed the air vent? Might be airlocked if old AAV is crusted up, nowhere to vent to? Is the new pump bled as well?

 

[Destroyer2813]

Is the main hex rippeled

 

[moony]

Yeah changed air vent comes new with pump matey.... Pumps vented... I didn't check for ripples destroyer... But I will how severe are they have you ever seen one ?

 

[Destroyer2813]

If its really rippled you'll be able to see the interal waterways and if its sucked in the water is really dirty clogging up the waterways causing your rippelling

 

[Destroyer2813]

Did have a pic of one but its on the phone I broke

 

[Killy Bing]

This is a mild case of it happening

 

[moony]

So what's the fix for that a new heat ex? Anyone know the cost of part ?

 

[Destroyer2813]

Yeah new hex and a really good clean required, its easier to pass on to Worcester on a fixed price

 

[Killy Bing]
