Hiya,
Any vokera experts on this forum, just need some help with this boiler.

Boiler will work fine for a few hours then randomly will lock out and then will re start after a few hours.

Red LED blinking and the rest are off. Vokera manual says HIGH limit thermostat fault.

1. High limit Stat tested working, however still replaced with a different one.
2. PCB replaced.
3. Burner cleaned and electrodes cleaned.
4. Flow and Return NTC aprox 10kohms
5. No one answering at Vokera tech support.

Anyone had similar issues. thanks
