New Glow Worm boiler locked out on F83

[MCN]

I came home to a stone cold frozen bollocks hoose yesterday.
Heating 'should' have woke up after a 'vacation' period yesterday morning 06:00 (When I was sat sitting in the KLM Clown Lounge at Schiphol)
Well it gu king didn't come on.

Instead, I was welcomed by an F.83 error code flashing its tits off on the boiler display.
The bastirt was installed last October so has only worked about a year and only if I'm at home every other month.

F.83 come up as Dry Fire.

A temperature differential error
No water in the system.
Inlet outlet not connected the right was round.

Sensor faulty.

There's water in the system. I bled the wee stand pipe just above the circulation pump in the airing cupboard.
Water spurts out.
The top up tank in the loft is full. (Gtavity system).

The central heating controller works.

I cannot hear the pump running when I activate heating for water or radiators.
Normally when I increase thermostat settings on the controller the system clicks and the pump starts starts making a whoosing sound.

I might just replace the pump. It's 230v ac. I could fuk about running wires to it or putt a meter on it first though.

Any thoughts and prayers welcome.

Hmm

Pump not running measn the boiler won't fire - it it did it would boil which is bad.

You're righ to focus on geting the pump running. You say the boiler is new but what about the pump?

YOu can wire it up to a plug an connect via an extension lead to check. If it runs then theres an issue with the controls or maybe thethree way valve.

If the isolation valves on the pump aren't seized it should be a straightforward fix.

Rain blown into the inlet by yesterdays storm messing with the sensors?

It happened with my condensing boiler about 15 years ago just after the bastard thing was installed.

With a normal boiler, I'd be wondering about the thermostat(s) in the first instance. A duff thermostat could give you a temperature differential error. There's usually one upstream and one downstream. Should be simple resistance check of the 'stat although finding what it's supposed to be could be a bit of a fight. Assuming they are both the same though and that the thing is an even temperature because it's off, the two should give the same reading.

Thermostats are cheap.

Last time I had an issue on a boiler it was actually an inlet flow switch so the pump was coming on but the flow switch wasn't telling the boiler the pump was on so it wouldn't fire. Just a microswitch on a paddle that screws into the pipe so really easy to test them.

You should be able to test the pump itself by jumping a couple of terminals.

Airlocks on pumps happen too, they generally have a (seized) bleed screw on the top.

F83 seems to be a catch-all code for a number of issues depending also on the boiler typre. Steve Reid says..

I went with the bcf troubleshoot and remedy method.

Plugged in a bare wire to the upstairs 13a socket hot wired into the pump feed. (LNE.)
Pump runneth when power applied.
Selected 'In' on my passivliving control (mobile app).
System began heating up, rads warming. Walloper thawing out.
(My room stat is set to 20°C.)
Set passivliving control to 'Out'. To switch ac feed power to pump and boiler.

Reconnected heating control ac feed to pump.

Selected 'in' on passivliving control.

Pump started, boiler fired, heating running as normal.

Selected Hot Water.

Motorised flow valve turned from heat only to heat and hot water position.

So it only needed a 220v 13a kick up its arse.

It will all shut down at 14;30 and should come on again at 16:45.

We'll see if bcf has come through for the membership again then.

I've had trouble with the microswitches inside the motorised valves in the past The SOE is something like..

With Timer On plus Theromostat On controller gives signal to motorised valve that opens to either CH or HW or CH/HW - once the valve is open the microswitch enables a live feed to the pump, with the pump running the boiler will start and Robert is your Dad's brother.

if the microswitch is sticky pump no starty.

Does all this mean that something got wet, possible for an extended time. You drain off the water, but the boiler needed a kick to turn on. That then got everything hot and dry and working again.

Whilst I don't normally agree with the Stinkwheel view that combi boilers are more trouble than they're worth, it does sound like your situation is one where alternatives could be considered.

Is the pump confrmed nadgered? Valve can be had for about 75 quid and heres'a cheap pump.. dunno why it's lss than half for a Grunfoss though

The pump is whirring away on III quite as happy as a pump can be.

2-way valve 2-waying too.

But...

It's a maintenance thing, If it can fail it will and better late than never.

I saw the wilo pumps.

1/2 price but will it last as long as my trusty Grundfos?

The one fitted has been superseded to a different pump. So Ill have to read all about the pump curves for that as compared to the curves for the existing pump.

The agony of nae heat in the hovel when it's -2°C outside will kill me.

I don't do any of that boiler/heating inspection pish. I treat the system with Fernox and that has saved me more than the cost to treat. Drained and refilled every four years, I have two magnetic filters in the system now. I already fitted the fernox filter.
The cnuts who installed the new boiler insisted I that they fit theirs. Much more of an arsehole to service than the Fernox filter.
The system has Fernox F9 Protector and Filter Fluid in it too.
