We have a customer who purchased the above oven from us about six weeks ago and she has rang and said that the last few times that she has used the main oven, after a while the display would come up with ER03. If she turns the power off and back on and reset the clock, it carries on as normal.
Does anyone have any ideas what the error code is, before we go down the route of getting Bosch out to look at it.
Thanks
Merv
