Worcester 28i

[RichardEG]

Hi, all

I have a Worcester 28i combi.

I am having a devil of a job getting hot water intermittently.

It goes to fire up, there's an initial 'whoomph' of the gas lighting and then a 'clicking' from behind the temp knob and it turns off.

It only happens intermittently. I see PCBs for sale - is this my likely problem?

Usually

Tks for the quick response.

Whilst waiting I had a good search around this forum (it's good 'ere innit?) and found some advice to turn everything off for 5 mins.

Did that and we're working again now.

I'll keep an eye on it.

Cheers

Its had it. Trust me, they don't just get better.

I'll contact the guy on epay who does the recon pcbs as the new ones are considerably more expensive.

buy cheap...buy dear!!

get a new one...the recon will fail twice as quick...if it works!

I agree.

Thanks, guys

Can you recommend any sellers on line?

Bought one new, fitted today, works a treat.

Now I've just got to work out why the pressure's playing up in the central heating.

The dial reads low, so I top it up.

A few days later it needs topping up again!

Then I find the overflow outside is discharging.

Am I simply adding too much water to the system?

Refer to FAQs on repressurising expansion vessel. Try snapping the PRV shut a few times and see if it reseals, otherwise this will need replacing.
