My name's ***** *****. I have a Riva Advance HE boiler

Customer Question

Customer: Hi,
My name's ***** *****. I have a Riva Advance HE boiler and it's not working.
I have a one second light every two seconds on the left hand LED and the pressure is just over 1.
JA: Thanks. Can you give me any more details about your issue?
Customer: I've tried holding the reset button for 6 seconds and the 'lock out signal lamp' LED has gone red.
The LED on the left that I first mentioned is now a solid green light instead of flashing for 1 second.
JA: OK got it. Last thing – JustAnswer charges a fee (generally around $18) to post your type of question to UK Plumbing Experts (you only pay if satisfied). There are a couple customers ahead of you. We can help you for less if you're not in a rush. Are you willing to wait a bit?
Customer: Sure thing
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Just in case the pressure gauge is not right, can you put some more pressure in the system - can you take it up to 1.5 bar using the silver flexible pipe?

Customer: replied 1 year ago.
Just tried that but it doesn't do anything. The thermostat is at maximum so I'm wondering if there's a faulty connection between that and the boiler.

Perhaps the gauge is blocked?

Sounds like it may be time to get someone to strip it down.

Ok, thanks. I'll a plumber around to have a look.
