Potterton Suprima 30 Question

[kevinwebster83]

Hi

Hope someone can help with this. I have a Potterton Suprima 30 boiler and the Red light remains permanently on - is this normal? I've checked in the user manual and this light shows "Mains On" which is fair enough (although it never used to do this!) however the boiler never seems to fire up - even when i set the timer control to "On" although bizarrely we always have nice, hot water. Please could someone help, as i'm a bit baffled as to whats going on.

The boiler used to go into lockout every 2 minutes, so removed the PCB and i resoldered some dry and cracked joints which worked like a treat. The above only happened after draining the system to install a towel radiator but as the central heating is off then i'm confused...

Please help

Thanks in advance

Is your immersion heater on?, if so and the heating is off it is probably never getting a call for heat.

Hi

Nope, immersion heater is definitely off.

Then its working, no other way to get nice hot water

Hi

It is working, i was just wondering why the red light is always on and that the boiler never seems to fire up (the green light never comes on). When i do a reset, the green light comes on for a split second then disappears forever.

The only time the boiler has ever fired up is when i've turned the whole system off for a few hours and powered it on again, yet we still have hot water

If the boiler never fires up then you're obviously getting your hot water from another source!

Probably have a nice well insulated cylinder that doesn't require the boiler to fire up very often to maintain the temperature, try watching it after the water comes on first thing in the morning.

red light on is mains on as you know.

flashing green light is heating/cylinder calling for heat but up to temperature iirc, this is the one you should look out for as it shows the boiler knows there is a demand.

green light on is burner on isnt it?

like ollski says it must be working at some point in the day if your immersion is off.

you dont have a boilermate cylinder do you?

I have a Suprima 50 and that keeps locking out (red light on). But this is due to airlocks in the system which causes the flow thermistor to lockout. Keep bleeding the sytem but after a week more air causing airlock and water doesn't make it to the boiler. Pump works ok but makes a herrendous noise when no water flowing through before system shuts it off.

Had the boiler about a year and I'm wondering if something has been disturbed when fitted and causing a blockage. So would another drain and flush be in order?

If you've had it a yea rthren I hope its the HE model.

If it is open vented I suggest you have an incorrect pipe configuration.

Have you checked the 3 2 1 rule. Regards chrisey

red light solid - power but no demans

red light flashing = lock out or as we in the trade call it "you need a new PCB warning light"



I kid
