Leaking Worcester 240

[FredFlintstone]

Got a problem with my problematic old Worcester 240 combi. I woke up in the night to hear a drip drip dripping from the boiler cupboard.

It was leaking out of the bottom of the boiler so I took the cover off and found that the source of the leak was from the inside.

You see that pipe, the water is coming from the left, where it enters the gas flame bit (I don't know what it's called!), running down the pipe and dripping from the lowest point into the boiler. Where the water is dripping onto is the timer an electronic stuff but the boiler still seemed to have power. Anyhow, I switched it off at the mains to prevent further electrical damage but now need to know what the problem is.

I figured the leak is either the water in the system or from the mains that passes through to be heated (although there was no hot ater being sed at the time I guess it has standing water in it when the hot tap is turned off).

I drained the CH system from the lowest radiator and now the leaking has stopped so I'm guessing it's something to do with the water in the system rather than the mains supply.

Any ideas of what it could be and where I can start looking?

Cheers in advance for any help. Hopefully it ain't terminal because as much as I want a new boiler, I can't afford one just yet.

It sounds as if its leaking from one of the screwed flange connections onto the heat exchanger.

To repair properly it means draining the affected part and removing the heat baffles and replacing the washer in the joint. Just tightening might effect a temporary repair but commercially we would always replace the washer for a customer so that we can guarantee the work.

Since this involves dismantling the combustion chamber it should be done by a competent person usually CORGI registered.

will most prob be leaking auto air vent.Means removing outer case to check inside.AAV on top left of heat exchanger you will see brass valve with plastic dust cap on it.

Cheers folks,

If it's owt to do with the gas then it'll be a call out job methinks. Fixed the boiler before but if there's a risk of me doing anything incorrect with the gas then I'd rather pay someone who knows what they're doing.

Sounds like it's more of a labour cost than parts cost - I know someone who will fix any faul fr £65 plus parts so may go down that route.

Thanks again.

Nice one folks. Bang on the money - perished washers on the connection at the back of thhe heat exchanger. Mate had to remove the heat exchanger and fan and replaced fibre washers that had disintegrated.

Couple of hours work for him, £65 fee (no fix no fee) plus parts. He didn't charge me for parts as it was only some washers.
