Recently the electric motor of my water distiller just stopped working (as discussed in other pages).
After some struggle, I've finally found a new electric motor and was able to make the appliance work again:
However, there was some gimmicks along the way:
Wires, cables and connectors
- The entire wire + connectors between the motor and the power source needed to be redone and several parts required use of insulating tape (originally there was none).
- The blue connector is very close to the radiator fins although not touching.
Originally there was no such connector and the wires were just soldered.
- The yellow connector is using insulating tape while the original used transparent rubber.
- Originally there was no insulating tape over the thermal protection 'jacket'.
- Power supply cable touching the radiator fins.
Minor differences between the electric motors
- The coil of the new motor is 'exposed' while in the original there is some kind of 'tape protection'.
- The new motor has a shaft thicker than the original motor, which required a new propeller.
- The shaft's bevel was extended in order to keep the propeller at the same original height and not touching the top case.
Considering I'm not an expert on the topic, I still feel somewhat insecure to turn on the boiler. Things get pretty hot near the radiator and I'm not sure I have protected everything properly:
- What is the purpose of the 'tape protection' over the coil of the original electric motor? Should I reproduce that on the new electric motor?
- The insulating tape I've applied should be able to withstand the heat?
- The distiller was properly repaired and reassembled? Is it reasonable to expect that it should last again for several years? Is it safe to use it like that?

According to some advices, the power supply connector was too close to the bare metal chassis.
To solve that I've completely reworked the connection:
