Went to this machine the other day. The customer had pulled the machine out and taken the top off to investigate but was unable to diagnose the problem of a penny stuck in the pump 😆 After sorting this out I carried out my electrical safety checks only to find the outer cabinet was not earthed 8O. When removing the top of the machine the customer must have removed the cabinet earth screw which is very close to one of the screws which hold the top on. He said he only took the two screws out of the top 😉 the earth screw had been in place at some point as there was a witness mark.
It seems crazy to me that you can make this machine dangerous without even taking the top off. A label would be good say DO NOT MOVE THIS SCREW
