Boiler not working. How to check heating pump.

Are you turning off the system before you remove the screw?

Hi my pump has a lot of water coming out nonstop from bleed valve and it blows fuse in pcb when heating is on but works ok on just hot water do i need new pump?

thx our heating wasent working your banging the pump has it working thx agen.

Thank you so much for this! My boiler was disconnected at work for an extension build and when I recommissioned it I had fault F75. I was getting ready to change the sensor and even the pump but after seeing your video I did what you said and the pump came right back to life. Cheers

I’ve taken the locking but off but the water just constantly runs out when I do this. On your video you only have a small amount of water come out. Can you help?

Further to this the downstairs radiators come on for a short period before going off but the hot water and upstairs radiators work as normal

Hi Jonnie every time I switch the hot water switch on it trips the electrics out. Plus when I’ve also undone the plug on the pump loads of water comes out could this be the problem

Hi I’ve taken the lock off but water continuously pours out of the pump and is very hot, the internal part turns freely but when boiler is running the pump makes no noise. Can you offer advice?

This video was my salvation. Better than the engineer who came to my house, it was me thanks to this simple demonstration of professionalism. 🙏🏾

Thank you very much! I fixed the heating pump on your advice, thank you!

This trick got the pump/boiler working last week, but this week the pump seems to be overheating again. Is there anything else to do to tune up the pump?

When you remove the center screw should this device be plugged in or not? Thanks!

I can feel my pump vibrating and its very warm, even hot to the touch. I haven't unscrewed the large screw yet which ill do tomorrow and also unplug from the electrical socket.

Is the pump suppose to be hot?

when I run the bath, then after a minute or so the pump produces a clear whirring sound for 10-15 seconds before settling down. what could be causing this? is there an easy check/fix ?

A million thanks for this video. On the coldest night of the year In Scotland so far, this saved the day. And the emergency plumber's bill.

This is amazing, I was desperate and couldn't get hold of a gas engineer.. I wacked the pump hard several times and wow! the pump stated vibrating, and the boiler came on.. should I get a new pump?

Thanks mate

Super ,Thank you very much.

If the pump does not work will you have only hot water or nothing at all (no heat, no hot water) ?

Yes you should point our electric to the boiler needs to be (switched off) before doing this.

This video shouldn’t be alowed and nobody should be removing the front boiler case if you are not gas safe registered.
The boiler case is an important part of the combustion process and the seal around it must be re fitted correctly otherwise it could have deadly consequences

thank you thank you thank you 1000000000000000000000 thank you You're a lifesaver I fix my boiler thank you

Do you need to turn the water off
Or heating system

Do you need to switch off power off to do that

My on spins but doesn't work

Hit the pump with a hammer and bingo working again thank you spot on.

Thank you so much..sattle my problem

Thank you very much….my vaillant boiler wasn’t on for over 1 year as I’ve been away and when I come back didn’t work…..I’ve seen your video and I have done exactly the same and now the boiler is working fine
Thousand thanks for this
God bless you

Fixed my frozen pump! Made my day, thank you!

hello . do we have to decreese boiler pressure to 0 while this operation ? thanks

Done that and the pump moves freely.
Still got 1/3 of the rads that are luke warm and the rest cold.
What would be the next to check ?

Firstly you should mention that you should turn the power off to the boiler in case it kicks in whilst you are fiddling about with that small screwdriver in the pump. Secondly on the pump label in the 5 o clock position is an arrow - that is the direction of the pump - if you start turning it like you did in the opposite direction there is a good chance you will damage the pump vanes causing loss of pump pressure and having bits in the pump cylinder that will damage other vanes.

I can see my pump is spinning when I remove that threaded plug but the radiators are still cool to the touch. Could the impeller be broken? Is there any way short of draining the system and removing those four hex bolts and taking off the pump to visually inspect the impeller?

Thanks for video. very clear. ok removed the front nut, turned the inside screw- action seems fine...so put it all back together...turned to heat mode...the pump casing itself is getting very hot, is this normal? I can feel vibration and assume water passing through...I have hot water fine...but I only have two large cast radiators on this system, I dont believe they have water in them...as bleed valve produce nothing, but both cold as stone...even though boiler has kicked in, pressure at 1.6...any advice?if I open the feed tap the pressure goes up but not going to the rads.?
TIA combination boiler.

"Check heating pump"? There's two pumps... pump one is oil pump and pump two is water pump. Your video refers to a water pump.

Just waited 5 freezing days for the Ideal engineer to fix our boiler which was one year old and still under. warranty. He did exaclly you did!

Hi.. My pump is seized ..IV brought a new head.. is that a simple fix or replacement if I did it myself?.

Where do you find this pump?
I have an ideal logic combi boiler, but cannot find this part.

Good way to blow your pcb.

Mine cums allot of water when open this man.

You have to ensure the heating is off before removing the screw?

Thank you for perfect advice!!! You saved my day!!! Thank you!

Please clarify this bit as the tool landed and blocked the word out "if you give it a sharp tap its (what?) the pump off"

You want to make sure the pump is isolated before you take that screw out .

There is electronic device on the pump (wilo) i dont know how to remove it

ALL NEW PUMPS LOOK HARDER TO CHECK , HOW DO I CHECK IF THE TURBINE FROZEN

Bad advice, NEVER bang a pump or anything, do NOT remove👎 the VENTING screw while full of water, that's dangerous water damage PCB.

screw is stuck, any tips on how to loosen screw?

Thank you i had that same problem with the Utica 150 boiler and i had that 110 error message and this video helped me fix my problem thank you again
