I complained to the letting agent, who promptly told me that I was incorrect saying it was the motorised valve, and told me to use the immersion heating rather. Got hit with a 600 euro bill this month. But now I know I am correct and am going to stick the bill right to the letting agent and tell them to get a plumber in here asap.

From the start of your video I knew I would get my heating to work, you have that look of wisdom about you. July gone I had a Google Nest installed heating was working fine when tested but hadn't used it since then - called the tech that installed the unit, he did mention the valve might be stuck closed but failed to mention there was a manual override on the bottom, I couldn't see that part as it's in the boiler cupboard back to front hidden by pipework….not sure how they installed it! after a few burns to my hands and arms I managed find it and got the valve to stay open manually, there is resistance on the lever so I'm hoping I don't have to change it when it's back to auto mode, right now though I need to heat the house as its an ice box. You possibly saved me £200 quoted from the tech, as it seems an easy fix, can't thank you enough maybe I can buy an ice cold beer for you one day!🍻👍

For the last 10 years or so, I have had issues with the Honeywell 3 Port Diverter valve, in that I have suddenly only had Hot Water and No Heating. On one or two occasions I replaced the top-plate of the diverter valve because the ball-valve swivel had become stiff, but on all other occasions I have replaced the Actuator Head to restore Central Heating. On one occasion more recently, I successfully replaced just the motor in the actuator head (which was a lot less expensive). However, last week I woke up to find that we had Central Heating upstairs only, and the downstairs radiators remaining cold. Naturally I feared that the circulation pump had finally failed after 25 years of loyal service; but as a first step, I removed the actuator head from the diverter valve to visually check that it was OK and that the ball-valve swivel worked freely. I re-assembled and switched on the boiler, but the same symptoms prevailed. Therefore, with the boiler still switched on and in Central Heating only mode, I checked the voltage on the circulation pump - ZERO!! - so the fault is somewhere else! With the supply to the burner disconnected (so that I could lift the control panel & it’s box of tricks out of the way) I removed the cover from the Diverter Valve Actuator Head, hoping to see how it worked when switching between C/H & H/W - it seemed to OK, but still no voltage at the circulation pump. With the intention of changing the Actuator Head yet again, I started to slacken the two screws securing the Actuator Head to the Valve Body, when I heard the Circulation Pump start, and yes! - 240 Volts at the pump!! Evidently the limit switch inside the actuator head was not being activated, but worked fine with the actuator head securing screws backed-off by about one turn. Leaving all as it now is, I put everything else back in place and reconnected the burner, and It’s now bee working normally for the past 6 days without the need to replace anything - just slacken 2 screws a bit! Long may it last!! Hope this might be of help to someone, but be VERY careful when working on the boiler with the power ON!! 19/02/23

Heating is constantly on and when temp is not the desired one it will send signal and boiler kicks in and starts heating the zone it needs. First floor heating stopped working and I did move this lever to manual and it was giving proper resistance when moving. Now the first floor heating works when ground floor heating kicks in. Now my question is: Is it still faulty valve? why boiler does not start? I can't find diagram that would tell me what is giving signal to start what, I thought thermostat -> control unit -> boiler -> valve. but no idea...

Hi, we have the ST9400C next to the boiler and in our house the CM927 thermostat. The water heating seems to work fine … the heating this year we are having a slight issue. The heating comes on at the right time and the radiators all warm up - but when the thermostat reaches the correct temperature the radiators do not switch off. I have checked the pairing between the CM927 and the little box (HC60NG Relay Box) on the wall beneath the ST9400C and they seem to be paired OK. The flame does go off of the main thermostat (CM927) when the heat reaches the desired temperature and also the green light on the small unit goes off (HC60NG Relay Box) . But the radiators seem to just stay on … where as before the radiators used to switch off at the desired heat. Also when the rooms reach the desired temperature - the boiler just stays on. Do you think there may be an issue with the Honeywell Home V4043H 1056 zone valve, we seem to have 2 of them. We can use it as it is - just turning on and off by the boiler as and when - but would ideally like the thermostat to work. Any advice would be greatly appreciated.

Hey Al, thanks for the great videos. If I put the actuator in manual position and that does not cause the boiler and pump to start, is it likely a problem with the microswitches instead of the motor? My symptoms are hot water working but suddenly no heating. The valve is open in the manual position because if I put hot water demand on by turning up the cylinder stat, the boiler and pump start up and water flows to the rads. However, even though there is heating demand, as soon as hot water is satisfied, the boiler and pump stop.

I've changed a few heads on these valves in the last 30 or so years. It used to be the motor burning out that was the weakness but now it appears to be the mechanism that operates the microswitch. I suspect the geared drive has worn and jumped and the arm no longer touches the microswitch. The last one I replaced had done this and the same today on a valve head fitted less than three years ago. Is this a known weakness, otherwise known as built-in obsolescence?!

Open the valve to manual that feeds the flow into the cylinder if the water gets hot then the valve is broken.

Do you ever see any problems with the microswitches in valve head? I have a new head to go on my system (S plan so a 2 way honeywell valve) and am hoping that is the issue. Standard F+E system and the boiler cycles with the heating but heat never gets to the rads (HW no problem). I am guessing it is a valve issue. Also hoping its the head as I don't fancy changing the valve body. Had a problem with the HW about 12 months ago and it was the head in that case.

Very rare to get a microswitch problem. How ever that is why changing the head is better than just changing the motor.

Good vid Al, I have the 3 way valve, which is about 12 years old. I've been having a problem with the heating not coming on when timer comes on but hot water comes on, which when I turn off the heating heats up, it's intermittent, being that sometimes it all comes on and heats up or only one or the other heats up, so am having to manage it. Would this be a fault with the motor electronics, I've taken the motor off and checked the spindle and that's nice and free.. I'm also wondering if a very old mechanical room thermostat can cause the problem, it doesn't seem all that accurate with the clicking on and off, but will be replacing that anyway with a digital stat soon. Thanks Dave.

Hi, I replaced the motorised valve with a new one as it was clicking and not staying on. It worked at first. However it stopped working. I took it off to take a look and now it seems that the little lever is not moving the switch/spring on the inside. It seems like i broke this new part :-( Any idea what i did wrong? Would the best thing to do be the buy another one and attempt it again? Thanks👍

Hi George, I would buy the complete valve as the body, is sticking maybe on some sludge and causing the motor to burn out.

Pipe above the valve is hot and that below is a tiny bit warm. Radiators are cold. Valve lever is fully loose. It's a hot water or hot water and radiators only system. Thank you anyone!

I have had this valve malfunction twice on me in the past having to call out an engineer. It has been fixed on both occasions but I wonder what the engineer actually did to get it working again. I've switched on and off and on again at the controller with no luck, so does the valve just stick or the motor not function? I'm interested to find out to save calling an engineer and wait for his arrival if I can rectify the situation myself. They do seem prone to malfunctioning! Cheers.

He probably took the motor off to check it was working then turned the valve head with a spanner to loosen it few times, it as it has more than likely been sticking. Usually after the summer.when the heating as not been on.

In my old house I remember having to turn the valve with a pair of plyers to get hot water to the taps - it was virtually seized solid and the motorised plastic insert had broken so no longer worked, well it was really old anyway. The problem then though was the valve then dribbled only stopping when the water going through got hot and I'd turned it back off again. Happy days......

The pipes are more than likely expanding on the joists or touching floorboards. You can lift the boards, cut larger noggins and lag the pipes.

These valves are a rubbish design. The valve motor is permanently energised when switched to heating so that means it's energised for 6 months a year. No wonder they fail.
