Thank you for your advice. I will replace it. It looks very similar from first look to the Ideal HEX?

I really do appreciate your help.

I have today drained the system and added the usual descaler stuff, perhaps I am expecting things to happen too quickly from the result of what they do?

Yes, got it in one!

Boiler has been causing problems for a few weeks, with poor supply to domestic hot water, hot warm then cold. I Have descaled and had system flushed. No improvement. Boiler fires on demand, DHW gets very hot, too hot! then shuts down with residual short term warm water to cold. I do not think...

Yes I did ensure the jumpers were in the right place. I have just replaced the fan control panel, wiring harness and diverter motor. I can pick up positive feed supplies to the PCB but still no lights on the front control panel. I am not sure what else I can do?

Yea I know it is a bad product. No display at all, nothing happens when switching on. have checked resistance across the fan on two outer contacts and is open. When power applied there does not appear to be an active supply to the fan anyway. No attempt to ignite. Tried two PCB's from working...

Picking up new boiler for the plumber to fit but do I really need this item? I have googled it and it comes up with the Logic series kit but not the Classic series. Are they interchangeable? Thanks, John.

Thanks to you all. As it seems unlikely it will be the gas valve at fault I will put the £75 to get a Gas Safe registered engineer around the Chester/Wirral area who has knowledge of Vokera boilers and have it serviced. If not, I will call the Vokera company for a recommended person as you...

I do not touch the gas side.....period. I have already said I had 25 years experience of Worcester/Ideal boilers and yes I was a Landlord. Now retired. So no subtifuge or mystery here then? I repaired and maintained 7 units over many years succesfully in between the annual certificates and...

The latest...... When I reset it a number of times it was trying to fire but it would start igniting and go Whoof, whoof a number of times gathering intensity and would eventually light and perform OK. ( A bit like winding over a car engine thats miss firing). If I leave it it will go through...

Four year old Vokera Unica 36HE been fine, now stopped. Fan works when switching on, it stays on for about 5 seconds, then stops, and after one minute the fault code 10 is flashing. I appreciate that is either an ignition, condenser or gas supply problem? I do not want to touch the gas side of...

British Gas version. Have checked all connections. All correct lights on. No ignition on either CH or Domestic. Pump running continually. No problem with wireless thermostat. PCB looks clean and free from damage. I am reluctant to pay £150 for a replacement board if it is likely to be another...

My meter reads from 100 on the left to zero on the right. The measurement it produces is 4. Hope that helps. If you can imagine the sweep of a windscreen wiper it goes 70% of the travel.

when in position and switched on I get a live on both terminals with my neon tester. When testing the resistance it returns what is best described as around 75% on the meter, the same on both solenoids I tested. Thanks for your help

The water valve I suspect is faulty as I have replaced the solenoid. If I take out the valve the sprung loaded seal will lift if I blow through it and will move if I hold a strong magnet against it. When the water pressure is applied the valve will not open with the solenoid detached with the...

Gas fitter has left it to my choice but has specified Kw range. I do not want Worcester products thanks......unreliable with experience of six of their boilers in student lets. I can get a new Vokera Unica 36HE with a DHW flow of 14.7. (yes we have checked the incomings) for £640 delivered...

You guys were right to ask me to check incoming water supply. What appeared to be excellent is in fact only 12L a minute......can I get the Water supplier to change this? Daft question I guess! The outside stop cock is connected to a lead supply for a few feet then married to plastic pipe to...

Thanks Glasgow gas for that comment........ what I am after please is whether the 35Kw will suit rather than going for a system boiler. The plumber I use is happy to fit but prefers me to make the choice of boiler hence the request to know what capacity I should be looking at and prefer to stay...

Thanks for that....I am looking to have installed a new combi so am asking what spec to go for please? There is no issue with incoming supply, but I will check tomorrow. If the supply is as expected what KW boiler do I need please? I am currently looking at the following; Vokera Unica 36 at...
