Mend Worcester-Bosch 30Cdi Heating Hello Boiler Noisy

Heating problem with Worcester-Bosch 30Cdi?

Hello

The boiler became slightly noisy while normal operation. I switched it off for a while and on again after a while. Hot water seems ok however heating seems to be working at reduced level and the display flashes the sign:

| |
- -
| |

together with the temperature.

Can anyone tell me what the code stands for? I cannot find it in the error codes. And ideas on what's required would be great of course. The problem is that due to incorrect tiling I need to cut off the tiles to access the boiler.

Thanks Matt!! That's such a relief to heat. In fact the code went away.

I got a bit worried by the noise first and thought that was an error code for some fault. Yes, not only did I do a reset but during it and I also switched it off at the main. The noise has gone now. I wonder what it was! Will cut off the tiles so that an engineer can properly access it next time the service is due.

i think u will find its the code for the syphon filling cycle.. if uve turned the mains off the boiler does this everytime the power is tuned back on .. 2 ensure the condense trap is full of water ..for approx 10 -15 mins , complex i know !!! is the temp selector for the heating turned up ?
