Boiler problems

Russinating · 3 Feb 2014 at 21:03

We've got a Worcester boiler and Drayton Wireless System. Past few days the heating has been going off randomly and now won't turn on. The Digistat shows the current temp (14c!) and a flame to show the heating is on when set to anything above that but the boiler isn't doing anything.

We've got hot water and you can hear the boiler turn on when we run the tap.

If we set the temp to below 14c and then turn it back on again then the red alarm light flashes, the green on light comes on but nothing happens.

Help, we're freezing!

After all those more complex suggestions I replaced the batteries on the transmitter and it seems fine! Will keep all the above in mind if it starts playing up again though.

Guess we all assumed you would have tried the batteries and override button before posting for help

Well there was no battery symbol which according to the manual there should be, we had a gas check 2 weeks ago and the guy replaced them, and it worked (ie the receiver flashed and turned to on when the transmitter was changed). So, yeah

. I'm guessing the gas check guy fitted duds or picked two up from the wrong box.

I would have done it straight away if it weren't for the above, plus didn't know if it'd have lost its partner/connection with the receiver by powering it down.

Ack! So it appears a battery change didn't fix it permanently. And our internet works now so I can post some pics.

Transmitter. On manual, flame icon comes on when temp increased about current and visa versa. No other icons.

Receiver. When flame icon comes on, alarm light flashes red ~10 times and then the green on light comes on. Visa versa happens when temp is reduced. Whether the boiler actually comes on with the green light is hit and miss and it seems it goes off randomly as well.

Boiler. Not much I can tell from this! This was taken with the transmitter flame icon on and receiver green light on.

Thanks in advance.

The heating is on now and the boiler pressure is at 1.5 bar. So it seems sporadic more than anything.

So did you add any water ? As Chris says it shouldn't run with zero pressure.

Nope, didn't add any water. In the original picture I think it was on 0.5 bar as opposed to 0.

Russinating: Replace your rf thermostat! Fit a Honeywell. And get a boiler person in to recharge your expansion vessel.

Renting so up to my landlords

. Will see if it carries on and then get in touch with them if it carries on playing up. Going on holiday for a week next week anyway so might stick it out until then and contact them once back.

Right back from holiday and it's still playing up. Think I'm going to go with The One's diagnosis. Found this video: http://www.youtube.com/watch?v=uQc0eyOKvwE. Is this what you mean The One or is the relay a different part?

Haha, fair enough. That does seem to be the problem though (ie light comes on but no click) and a bit cheaper at £3.99. May as well give that a go first anyway I guess. Have a solder so should be a quick job.
