Qooker tap. Poor boiling water flow. Hot/Cold flow ok.
Discussion
Looking for a little guidance, as the Qooker technical support is quite poor, as in; any questions posed to them are being ignored.
Initially I thought the decreasing flow on the boiling side was probably down to a filter, so ordered the kit, cleaned out the scale, fitted my new filter and seals etc to the cyl and then tried out the tap. My expectations were not met...
It still had the reduced flow and splutter I was trying to cure.
The nozzle/spout has been descaled comprehensively, and is fine.
The hot and cold water flows are fine.
I then looked at the faq, saw they were suggesting a new prv; which for us was unlikely to be an issue, but I did as anyone would do, I gutted it. It's not needed as our pressure here is frankly dire, only around 2 bar ish.
No improvement with the prv gutted.
So PH what have any of you good folks come across that I should evaluate next?
Possible a hose with a calcium build up, I'm asking as I don't want to just force anything down a flexi hose, with the risks of damage, especially as the one leading to the tap itself is extraordinarily well hidden by an under sink installation, and if I tear it, it's going to be one hell if a job to get it all out and repaired .
TIA.

As a point of closure on this.
Qooker did eventually reply a couple of times, one of which said to check the silicon hoses inside the unit that feed the supply to the vessel from the top to the bottom.
I had already checked this out, and it looked clean.
However this time, I decided to remove all the hoses and try to push through some 1.5mm lighting cable.. stiff enough, but delicate enough do as not to damage internally the hoses.
As ever, it's always the last hose that gets checked that's the problem, and in this instance it was indeed the supply from the prv to the top of the cylinder that was indeed blocked with scale, even though it flowed ok when a hose pipe was attached.
Picture attached to show what it looked like in case it helps anyone else out in the future.
So my system is back to full flow, with a gutted prv; as I felt this was just another restriction that didn't add anything to the party. Our water pressure is poor anyways, so unlikely to be an issue long term.

Is the softened water any good for drinking?
The other option is to just hop on Amazon and buy 2Kg of citric acid for >£5 and to periodically descale the hoses in a bucket.
Seems odd the hoses got scale in though unless it fell out of the boiler? Missing a mesh filter washer in the design?

Softened water is fine; the salt is for cleaning the resin on a backwash, so not an issue.
Citric acid is meh, imho, tried it in a variety of ways, and it's far less efficient than good old chemicals.
It's not an easy task to disassemble the whole thing given its location, so softened water is likely to be the long term solution (pun not intended) removing the hoses, prv etc takes a good morning or so to do, then there the washers etc to remember to replace, leak checks , flushing etc, so you could say goodbye to the best part of a day, depending on how you go about it all.
Scale is just a problem for us, readings here are 380+ so very hard water... learning to live with some aspects is just the way of it all, and the cold water feed is used for watering plants, fish tank and other bits that wouldn't benefit, so I'm planning ahead, but it's not going to be yet.
Anyways, this was a point of closure mainly to help anyone else finding themselves in this situation, hope it helps.

Our is fed with softened water. It was "protected" by the old scale control tank before but loads of scale still flaked off from inside the tank when previously serviced.
When it was serviced earlier this year, the engineer asked if I was adamant that I wanted it serviced as he reckoned it didn't need it with softened water. I had it done anyway and there was no scale when he opened it up.

No scale control fitted, though I am pondering adding pipe work from our water softener now..
If you have a softener then connect it to it, its a no brainer. We connect all the Quookers we fit to our softeners.
You will get no more limescale.
No more once a year descale service, if you were doing that.

Servicing a Quooker fitted to a softener can take place every 4 to 5 years. When it was serviced earlier this year, the engineer asked if I was adamant that I wanted it serviced as he reckoned it didn't need it with softened water. I had it done anyway and there was no scale when he opened it up.
Thats to change the HT carbon filter, a little sooner if you have the combi tank.
