I have an Ariston Genus boiler. Fault showing 30 40 50, I can't find manual?
Why does my boiler remain ON - even when switch is moved to OFF?
What is the problem?
Ariston Microgenus 23 MFFI PCB Defect?
error code e02 wont work when pressurised?
Error light blinking (orange colour) on Ariston e-combi boiler?
