I used a vacuum cleaner nozzle on our inlet side and dislodged the trunking. I went into the loft to refit it and was amazed at how much dirt had accumulated on the fan blades. Used a small brush to clean it and its efficiency improved considerably. You could see steam being drawn into the inlet.

We have a Logik HE balanced flue gas fire which has recently become awkward to ignite. If I try to light the pilot, using the prescribed method, nothing happens. However, as I move the lever towards the high flame position, the fire suddenly lights, quite dramatically. The fire was serviced...

No Opentherm, and the heating has been fine, and still is as far as I’m concerned. It was just witnessing this, hopefully, isolated series of events that got me thinking.

we have a Baxi combi 800 boiler, 1.5 yrs old, and I have the heating flow temp set to 65 degrees. Today I just happened to be beside the boiler which had been sitting idle most of the afternoon due to unusual warm weather. I noticed that the water temp indicator displayed 26 degrees, and the...

I have an electric shower which has suddenly stopped heating the water. I have checked everything, that I can, inside the unit and get all the continuity’s and resistances that I would expect. I get 240v when the pull cord isolation switch is on. Obviously, I cannot check the supply on load...

Problem solved. New selector switch delivered and fitted, lovely hot water now. Great outcome, only £43 spent plus massive boost of self satisfaction.

Yes I’ve got 240v. Is there a way to troubleshoot the selector switch. I have ordered one anyway as I can’t find a fault elsewhere. Failing that it’ll be a replacement, but finding one with a similar footprint may be difficult. I’ve noticed the current Mira showers have fixing screws in...

Both elements read 13.8 ohms

I ran it for quite a while this morning but didn’t notice anything untoward, although I wasn’t concentrating. I’ll try again.

we have a Mira Zest 8.5Kw shower which has developed a problem. I can switch the power supply on using a cord pulled switch, turn the shower on but only get cold water regardless of the temperature setting. I have checked the thermal switch and get continuity, and high resistances in the heating...

I took the battery out last night and the temperature dropped to warm. I’m going to get a new battery today.

Thank you Sparkymarka, have removed battery and will seek replacement tomorrow. Do I have to get the exact replacement, 2.1ah or would the 2.3ah suffice.

the control box on my scantronic 9450 alarm is very hot on the top surface, not too hot to touch but significantly hot. My wife is concerned that it may burst into flames. I could pull the fuse, to disable the box, but would need to delve inside to disconnect battery. Tomorrow I’ll arrange an...

The battery is at least 10yr old.

We have a bay window in a bedroom with a wooden internal windowsill, which is made of three boards mitred together at the angles. Despite my best efforts, when decorating, cracks appear along the joins after I have filled and painted over. Can anyone suggest a really good filler which may...

Would the third wire go all the way back to the consumer unit? Seems a bit excessive. I had so much bother that I can’t bear to remove it

Today, to make it easier to apply wallpaper, I removed a double socket. When I came to replace it I had problems connecting the earth to the socket, because there seems to be too many. On inspection there is, as expected, 2 live wires, 2 neutral wires but 3 earth wires entering the back box. 2...

Haven’t fully investigated, but I’m not sure if the cabling has sufficient slack to pull down when wiring the junction box.

My wife has seen a new light fitting in our local IKEA which she would like to replace an existing fitting. However, the new fitting only requires a live and neutral feed to its junction box hidden inside its body fitted flush to the ceiling. Unfortunately, the wires supplying the current loop...
