Before you start

Unplug the appliance and shut off the water if needed. No check is done with the appliance powered on.

Do not open a refrigerant circuit, do not work on gas, and stop everything if you smell burning.

When in doubt

If the risk is high or you are unsure of yourself, contact a qualified professional.
