The fridge will have an evaporation tray in the back on top of the motor, if the fridge was left open this will be overflowing. If you pull the fridge out the tray should be accessible to clean. That should stop the leaking (it will stop by itself but better to clear the tray anyway)
So sorry, was planning to be at the space this afternoon but unfortunately something urgent has come up and I can’t make it. If anyone else has seen this post, please can you assist with clearing the leak.
If they are more energy efficient that would count in their favour. Main issue with kettles seems to be boiling much more water than is needed? Plus they aren’t thermally insulated.
