Model: Hotpoint Ultima Extra WMA62 Problem is that when drum turns, eg during wash, spin or simply by hand it makes a clonking like the drum is being tapped firmly. But you cannot feel the tap when you turn the drum. The problem occurs in both directions. I have removed the belt and the noise...

Hi, Advice appreciated. Have fitted a fourwinds timer contolled water softener. It's model E10T which looks the same as the one wickes sell. Problem is that the regenration process only seems to be effective when the salt tank is manually primed like when first installed. The...

Thanks for all your advice. It's been essential in helping me understand situation and realise the wiring fault. Currently owner is using the HW stat to turn off water when not required. Inconvenient but works fine. Now that I think I understand the circuit I'll see if there is opportunity to...

Good and bad news. The HW stat was wired up wrong and fixing that has meant the diverter is never powered if CH is not calling for heat. That's sorted. The bad news. I can't have CH without HW. The diverter needs to be powered for CH. Terminal 2 on the HW stat is the only source of power...

I didn't get from honeywell site as need an account but it's knocking about in other places for example: http://www.jl-heating.co.uk/downloads/w_plan.pdf Quote is third of way down on 2nd page. I think wiring fault is just cables to HW stat terminals 1 and C wrong way round. I'll get a...

I can now see wiring faults. For example HW stat Common is the power-in from mains switch as opposed to going out to the switched boiler feed. This is part of the reason diverter is always powered when HW stat is not calling for heat. All the wiring needs to be reviewed against the W plan...

Sorry, I should have said Normally Closed i.e. the connection that would be powered by the room stat when not calling for heat.

I think the limitation must be the simple 3-port valve which has to be one or tother and not both. This is what I've found out (or I think I've found out) for this installation: When power switch is on, power goes permanently to boiler, COM of HW stat and COM of room stat. When HW...

HW thermostat is L641A1039 CH Thermostat/Programmer is Grasslin ECO ET2 Digital Thermostat Boiler is Potterton Prima 50B No timer or programmer overall or for HW

Hi D_Hailsham, Thanks for the info. That makes things simpler. Actually I have not yet looked in detail at the Y plan and would welcome suggestions. The problem with this W plan is CH cannot work independently of HW and HW is given priority. In this house there is a comprehensive...

It is a Honeywell V4044 with 40003916-002 power head.

Hi, Appreciate if someone out there can advise. I plan to upgrade the heating from the W plan to Y. Does anyone know if the brass component of the three-port valve is the same on both types of diverter. I'm was hoping to fit the 4073 actuator without replacing the actual 4044 valve to save...

Took the advice - and very grateful for it. Ran pipes together for a short distance where necessary. Suppose that in practice central heating hot water is not close to hot enough to cause problem for gas. No problems found. House didn't burn down :D

Hi, I'm sure many of you will know thissimple question. Is there guidance on how close a hot central heating pipe can be to a gas pipe? I'm adding another radiator. It's an old house with loads of cuts in the floor joists for vairous and past plumbing and electrics. So much so that the joists...

House is terrace about 200 years old with solid walls. There's a small section of external wall, about 1.6m wide, about two thirds below ground, joining a section of side wall shared with neighbour about 1m wide. I'm on a hill so neighbour's basement floor is about 30cm higher up. Damp was...
