Essentially, my customer has reported that the machine randomly displays error codes E03 & E16 I have run a quick wash and monitored the cycle. (fills, washes, heats, drains, rinses and fast spins all fine) so would appreciate some help. Many thanks, jonty July 22, 2020 at 5:46 pm #470715 Hollytree_TechnicalParticipant Have you checked the insulation resistance of the heater as this is known to cause this issue.

Kind regards, jonty Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
