OK so I did kitchen sink + bathroom basin and i9 and i11 temps were 80C-82C and 54C-55C. The issue didn't occur during a test duration of 2m30s. I also checked i6 which is the DHW flow rate in LPM and it was around 7.6LPM which is a bit lower than the bath mixer which usually shows around...

With the basin hot on full the i9 HEX temp is stable around 67C-68C and the i11 DHW stable at 54C-55C. I can upload a video if required. Thanks for your help with this, really appreciate it!

I have just retested and recorded a video of it: Start of video HEX 79C and DHW 50C For the next 1m30s the HEX temp slowly increases from 80C to 88C and the DHW from 50C to 55C At 1m 35s the boiler starts cycling off and on during which the DHW temp is jumping up and down by 5C steps...

This is what I did previously in post #8 with the video on youtube. My wife is at the bath saying how the water feels but it may be difficult to hear. Here is how it goes: The water feels hot at the start of the video and then at 33secs in you can hear the boiler click off and the waters stop...

So you want me to feel the water coming out of the bath filler compared with basin? Those readings of 67C and 90C are from option i9 on the service menu, which the manual says is 'the actual temperature from the main heat exchanger displayed in real time.' So they're not the DHW flow...

The DHW and CH are both set to 55degrees on the boiler. Should I try it lower than this?

Sorry I am struggling to understand how the HW flow can be restricted if there is 9.6LPM from the bath, wouldn't this be a lot lower if it was being restricted? I was thinking the opposite, that the bath has the highest flow rate in the house and the boiler isn't able to heat that demand quick...

I've measured the flow rate at various hot water outlets with hot on fully: Bath in main bathroom 9.6LPM Basin in main bathroom 4.6LPM Rain shower in main bathroom 6.6LPM Handheld shower wand in main bathroom 8LPM En-suite basin 9LPM Downstairs toilet 8.8LPM Kitchen sink 4.8LPM I haven't a...

I just measured the flowrate for 30s and got 4.8l so 9.6LPM.

All the tests I have done are with the bath mixer on full hot, no cold. When I took the mixer apart and checked the cartridge it all seemed fine, it was closing the cold inlet when on full hot and vice versa, can't really see what could go wrong with it. Anything else I can check on the mixer...

The concealed mixer does the bath only, there is a separate thermostatic mixer at the other end of the bath for the shower. We do have high mains pressure (nearly 8 bar if I recall) but we had a PRV fitted which is set to 3 bar which I believe is normal? This is higher than the 1bar on the...

All the taps in the house are mixers unfortunately. If I run the basin tap (mixer) in the same bathroom it's fine, the boiler remains on throughout and the temp in the heat exchanger remains constant between 67°-68°. Below is a video of the boiler with basin mixer on hot. Apologies at the...

Below is a photo of the mixer. It is a Grohe 33963000 Concealed Mixer. It's not thermostatic. I took it all apart and there wasn't much crap in there just a few tiny bits of black stuff.

So the issue has started again and I managed to observe what the boiler does while the mrs checks the temp at the bath tap. I recorded it with a video showing option i9 from the service menu which is the temp from the main heat exchanger and uploaded it to you youtube below: The water is hot...

With the CH heating on the hot tap is fine. The issue was when the CH was off, then the temperature of the hot tap would fluctuate.

Well to my amazement I have tried multiple times today and haven't experienced the issue at all. Really confused. From what I remember the boiler was cutting out when the issue was happening. If I recall correctly the flow temp in the heat exchanger was getting above 90° and would then drop...

Hi, We've got a problem of fluctuating hot water from our bath mixer where the water is hot and then a minute or so later will go cold and then few mins later will go hot for a bit and then cold again. No other taps in the house have this issue. I took the mixer apart and checked the cartridge...

Hi, We have fluctuating hot water when filling the bath so I have taken apart the mixer to check the cartridge and filter. When I look inside at the filter it does not cover the whole opening, is that normal? I have tried to find a picture online but none show this view. The cartridge is GROHE...

Could try an oil based primer like Cover Stain?

I was wondering if anyone has experience spraying Zinsser Bullseye 123 primer with an HVLP? I just repainted an internal door at the weekend, first priming it using BIN with a foam roller and then spraying scuff x with a HVLP. There was clear orange peel effect after the BIN. The result is ok...
