Heatline Monza 28 - Symbol, not fault code displayed ?

[Manicuk]

Hello,

Any idea what the symbol below means on Heatline Monza 28 combi boiler display ?

-||-

Fault code F20 overheat was original problem resolved/cleared after reset, but has now progressed to the above symbol.

I first thought was LCD issue but normal op shows full digits so i assume its a symbolic fault code (maybe valve?)

I'm not a boiler engineer nor do i pretend to be, but i can read.

Any advice appreciated

Thanks

Thanks Muggles

Now i know it represents/prompts the reset..
Now i need to figure why it wont reset as previous..even after power cycle.

Appreciate the manual, plenty for me to read in there.

I wont be tinkering though, just want to make sure the largest uk supplier is not ripping me off.

Thanks again
