What it is
The Vaillant cable tree, part number 256136, is a wiring harness assembly used to route and connect electrical circuits within a Vaillant heating appliance. It carries the low-voltage and control wiring between the appliance's electrical components, keeping the loom tidy and the connections secure inside the casing. It is supplied as a Vaillant spare for service and repair work on the manufacturer's standard water heater range.
Signs this part needs replacing
- The appliance fails to power up or does not respond to the controls
- Intermittent operation, flickering displays or repeated lockouts
- Fault codes relating to communication or sensor circuits
- Visible damage to the loom: chafed, cracked or heat-affected insulation
- Loose, corroded or discoloured connectors, or a plug that will not latch
Before you order
- Confirm the part number 256136 matches the number shown on the existing harness or in the appliance's parts list
- Check the appliance model and GC number against the compatibility list below, as Vaillant used different looms across its ranges
- Inspect the connectors and the components the loom feeds before fitting, since a damaged plug or socket can cause the replacement to fail in the same way
