February 21, 2005 at 11:44 pm #126779 Dave_ConwayParticipant Re: Hotpoint Aquareius DF41 – error code 20 From Hotpoint’s online info (their words not mine): “E20 – Temperature under range. Book an engineer.” Basically, it’s not heating the water which could be down to a few different things, heater, thermostat, control unit… Probably time to call an engineer as Hotpoint suggest, try the directories or repairs@ there should be someone there who can help.
