Hi, i work on these machines on a regular basis and until very recently i was a Meiko service engineer- the code ERR203 means that there was no change detected at the boiler level switch during emptying- be it on the fill or rinse cycle. This fault is mostly caused by the booster pump failing to pull water but could also be caused by blocked rinse jets or a faulty boiler level switch. Hope this info is of use to you , Kitcheneer
