What it is
The temperature limiter plug is a Vaillant component supplied under part number 252776. It forms part of the temperature limiting circuit on Vaillant VK and VKS 35/1 E, 41/1 E and 48/1 E appliances, where it connects the limiter into the appliance wiring. It is a small electrical plug fitting rather than a mechanical or hydraulic part.
Signs this part needs replacing
- The appliance locks out and the temperature limiter trips repeatedly
- Overheat faults that persist after the limiter has been reset
- A loose, discoloured or heat-damaged plug body at the limiter connection
- Intermittent or open circuit between the limiter and the appliance wiring loom
- Visible scorching or brittle insulation on the plug
Before you order
- Confirm the appliance model and production period against the fit list above
- Check the existing plug for damage and confirm the limiter itself is sound before replacing the plug alone
- Isolate the electrical supply and verify the fault at the limiter connection before ordering
- Have the manufacturer's parts list to hand to confirm the part number for your appliance variant
