Scalemaster No Display / Power to Electronics Lost

Display is completely blank but water still flows through the softener

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blown fuse or tripped spur, Failed transformer in Scalemaster power supply, Loose low-voltage connector, Faulty display board

Safety first: Turn off power at the mains before removing covers.

Step-by-step checks:

1. Check external power: Test the outlet or fused spur with another appliance.
2. Inspect plug and cable: Look for damage or overheating at the plug.
3. Open control housing: Verify that the transformer output is present (if you have a multimeter and competence). Check that the low-voltage connector is firmly seated on the PCB.

If the display remains dead with confirmed power, the transformer or PCB will need replacement by a technician.
