Vokera Mynute 16e

Frozenfred

Hi. Had a plumber out because the above boiler wouldn't start for me, he changed the circuit board, still won't start, said it's electrical. Electrician came, checked wiring, timer and stats, still won't start. It randomly worked this morning for an hour, but now it's kaput again. Neither plumber nor electrician can figure it out. Anyone else experienced this? Kids are frozen, it's been off for a month and I'm all out of ideas and cash:0(

Had a similar problem with one. Also changed PCB, fault persisted. Ended up being a break in one of the wires in the wiring loom. I was lucky enough to have recently upgraded a boiler so had an exact mynute as a donor. Was determined to find cause no matter how long it took me.

does the fan run,or do u get nothing,

sullzz

Common problem with these is the thermistor

Try Vokera, they charge 240 to fix any fault I believe.

Unless its a design fault then they charge for a new heat exchanger as well the robbing cheeky sods.

could be the micro switch stuck in a closed position.

Fred can you hear the pump running or any noise coming from the boiler when it is on??

DGOBS

More information is required to correctly diagnose, tell us exactly what's happening

The fact your plumber got an electrician says it all, 240v to switched live? Yes boiler fault, no control fault, even if the fault was a control he couldn't diagnose and repair he could link out external controls to leave u with heat!

240 for a repair even if parts are not required, are u mad?

When it worked everything sounded absolutely fine, but when it's not on, there's nothing. What annoys me is that it worked for a while today, but when it was due to come on at 4 and there was no sign. It was as if there was no power. Plumber checked before changing board, said there was no power going to the fan, but when he had changed the board it still didn't work. It was 200 quid for that beauty.

DGOBS

So why pay for it as I didn't solve the issue

No power to fan, what about pump, aps, water pressure switch

Where are u based?

240v to switched live- what's a control fault? Im a moron with this stuff...

Whats the water pressure gauge read?
bottom Lh corner, is the red light on or flashing?

sorry Tipp is too far for a flyin to you!

read my mind dgobs, im going to a lot of these after original rgi's have gone for pcb-pump-fan-leg it option and its been the thermistor. one particular development near me iv put in close to 20 in 2011 and 4 this year.

JohnnieK

Why do they always go for PCB's?

gdavis

cos they think if its not workin and the pressure is ok then it has to be the pcb!!!!!!!!!!!!!! obviously !!!

gdavis

and when they change them they hop back into their taxis and feck off !!!!!!!1

Pete67

This makes for depressing reading, and it's no wonder the public get fed up. Doesn't anyone know how to read a wiring diagram / use a multi-meter any more?

JohnnieK

Or step by step fault finding.

Who's to tell them, some don't have a trade background or they haven't been trained properly or they're just ****e;) who's going to stop them or monitor them.

Also ****e RGIs don't know their ****e, they think they're just really unlucky gas fitters who always find the boilers that need a PCB:D

Thermistor fault should give you a flashing red light

Hi
I have a Volkera Mynute 16e about 3 years old. The unit fails to ignite when required to heat the water and the red light appears and the unit has to be reset manual. This only appears to happen when the water is due to come on, the heating comes on as preset. The water gauge is at 1.5.
Can anyone offer advise

Fredrick

I have this boiler too. Few months back it would not start and had a red light. Rang a plumber and he said the boiler was caput and it would cost me over around 1500 for a new one.

After thrawling the web, couple of guys that had the same boiler said it was the thermistor so I went on ebay and bought 1 for think it was €15 all in, fitted it and all sorted, bit of a job getting it in but thats what the problem was in my case.

Best of luck.

Hi Fredrick thanks for reply.
Is it a difficult job to replace the thermistor and do I need to get a gas installer to fit this. As the heating is working well can I assume there is a separate thermister for the heating.
Thank you

Wow, it's like natural selection in action live on boards.

Yes, you would be breaking the law otherwise.

DGOBS

Doubt it's a thermistor as this boiler only has one, and it's working fine for CH.
Does the boiler fire at all when calling for DHW only, or does it lock out on first attempt without firing?

It attempt to fire up but then locks out after a few seconds without firing but works well on the CH.

DGOBS

It sounds like it has to be external to the boiler, like a zone valve closed or something as the boiler uses all the same system/components on both CH & DHW

DGOBS - i've been told on various forums that the ignition issue i'm currently experiencing with my boiler is a thermistor fault. So i've decided to purchase a new one (circa €25 from UK).
My question: is it straight-forward enough (i.e. not difficult) to replace myself OR do i need to call in an RGI installer?
Your help would be appreciated - my home has been without heat/hot water for nearly a week & i've 2 young children.
Thanks.

DGOBS

You are required by law to use an RGI to carry out work on you boiler

The thermistor fault would be indicated by a flashing red light on the flame failure indicator (hence why I asked)
But £25 from Uk is too expensive, about €20 from a local supplier (and no shipping)

Also the boiler will need to be drained for replacing this, and you may need a new prv too when this is done on this boiler IMHO.

Our Boiler is still having problems. We did have a plumber look at it and he suggested that the water pressure maybe the issue so opened the water valve for a short time, the system seem to work as normal. But after a week the issue returned. We are now going to do a check to see if we have a leak somewhere.

DGOBS

What is the water pressure when whole central heating system has been on for an hour?
Is there water coming out of the pipe outside (where your boiler is located)?

mishoo

DGOBS - do you know of anyone local to wicklow that you could recommend or are you available to carry out the work (i.e. change the thermistor) - that would rip me off or take me for a ride & concoct some bs in order to get more money outta me?
thanks

DGOBS WOULD rip you off alright :D.

NO. I'm messing;). I think there was a typo in your last post.

DGOBS knows his stuff and it always amuses me when people disagree or contradict.
If he recommends someone there bond to be good.

DGOBS

Sorry dont know anyone well enough in that area to recommend to you (sorry for delay also)

But a pretty straightforward job, max €25 for the part, would expect to get it done 'with a service' at no
extra cost but the part.

Thanks JK, imagine the amount of heads that read your first post, but never came back! no wonder the phone stopped ringing!!!

hi there i have a vokera mynute 16e too..it cut out lately because of no water pressure and when i filled it back up it still wont come on.. have a small child in the house and its getting cold.. is it the water pressure switch maybe? can anyone help please..

DGOBS

When you say won't come on, you need to be more specific, what does happen, any noises etc

polo99

the fan comes on for just half a second then goes off again.. the fault light flashes red.. iv heard the thermistors give trouble too!?

DGOBS

And that is exactly your issue, you will need an RGI out to fix though I'm afraid as it would be illegal for you to proceed yourself

polo99

cheers mate thanks for the help..

Hi I had a similar problem.my boiler would fire sometimes and not other so I changed the thermistor and it work ok for a few days then went back to the way it was in the first place.any ideas anyone
As it's getting colder now and it takes a lot of on/off pressing of the time click to get the boiler to fire

DGOBS

My car doesn't work some days when I turn the key, changed a spark plug and it worked, but now doesn't again. Think the mechanic could diagnose the problem from that?

Com

Dellboyryan

Ok well when the heating was turned on last night the boiler didn't kick in until 20mins later?? When you turn on the heating the boiler does nothing,no fan no pump no ignition no noise whatsoever but sometimes will start after a 10 to 20 mins sometimes not at all. Any help would be greatful

Thanks guys

Dellboyryan
