Faulty : Tecnik TKR621 integrated Freezer

[Laur]

My Tecnik TKR621 integrated Freezer has broken down and is currently showing a red warning light inside.

I don't have a manual and a quick google search says that a red warning light indicates a temperature rise.

Does anyone have a manual or advice as to what I can do to rectify/reset it?

Many Thanks

Laur

I've now found the manual but it's still not working, can anyone repair?
