Vokera 15 vhe Boiler

[mattgriff88]

Pump is probably wired incorrectly Matt, it should be wired directly from the boiler which should supply the overrun period, it's probably wired fom the zone valves auxiliary contacts that tell the boiler to fire when any one zone valve is open.

Ok thanks for your help.
Big/costly job to put right or easy fix?

Probably a few hours work but check first that your boiler has the overrun.

Hi Mate,

So I'm having a bit of trouble getting somone to do this job.
I have tried getting a couple of quotes over the weekend but none seems interested in actually running the cable.
The boiler is downstairs in the kitchen and the pump is up stairs in the bathroom. (Opposite ends of the house) probably not worth their time.

I have measured up and I'm looking at around 20m of cable.

I might have a go at running the cable myself and then getting a sparky in to connect up.

What size cable should I be buying?
1mm 3 core good enough?
Would it need to be heat resistant cable or anything special?

Thanks

Assuming permanent live mains is available where the pump is, there is a 'radio' link option that could avoid the hassle of having to run a cable. Here's an example - it costs about £100, so you might prefer hard wiring!

MAINSLINK is a plug and play solution to replace a switched live cable. When 230Vac “LIVE” is input to the transmitter; the receiver provides a 230Vac “LIVE” switched output at its screw terminals. When a cable run is awkward or expensive to achieve, the MAINSLINK can be used, saving time and...

Thanks for posting this.

looks like a much better solution.

Why not just install an overrun / timer relay on the pump so when it looses switch live it runs the pump for 10 mins etc

Eg

AC 230V 16A 1SPDT Multifunction Timer Relay On Off Time Delay Relay for Home | eBay

Output: 16A 1SPDT. 1 function of latching relay ( I ). There might be a bit of color distortions due to different computer resolutions.

Just want to say thanks to @John.g @Basher problem has now been sorted.

John was spot on with the pump not using the overrun function due to it being wired up incorrectly.

Bought one of these for £59.99 Mains Switch RF Pump Overrun Switch MAINSSWITCH01 - https://www.plumbarena.co.uk/product/mains-switch-rf-pump-overrun-switch-mainsswitch01/?gad_source=1

Had it fitted today and all now is running well.

Thanks again!

It sounds like your Vokera boiler is overheating when set above 53°C, leading to the error code. This could be due to a faulty thermostat, circulation issues, or a blockage in the system causing restricted flow. Before calling a professional, check if the radiators are evenly heating and if there's any noise indicating a pump or flow problem. Understanding these symptoms can help diagnose the issue more accurately and prevent unnecessary repairs.
