Drain gutter in fridge overflowing.
There are two thin wires that come from the terminal block and disappear up the overflow pipe (from the compressor end). I assume they terminate at a defrost heater but it feels like it’s lodged in. There is mains voltage across these wires but no continuity. Looked on Hotpoint website and others, but cannot find mention of a defrost heater.
Tremendously grateful for any help 😉
