Truma Caravan Water Pump Problems
Caravan holidays provide a unique sense of freedom, but like all complex systems, caravans can experience their share of technical hiccups. One such hiccup that has been identified by numerous caravan owners is an issue with the Truma caravan water pump. This article delves into the problem, its symptoms, and possible solutions to assist you in addressing this common concern.
The Problem
The core of the issue seems to be with the Truma Ultraflow water pump’s intermittent operation. The pump might run for a few seconds, then shut off abruptly. Users often find themselves having to constantly switch the pump on and off at the control panel to ensure continuous water flow. This intermittent behaviour can be especially vexing for caravan owners, especially when the setup is relatively new, as evidenced in the case of a Coachman Amara 640/6 2009 model.
Potential Causes and Solutions
- Pressure Switch:
- A frequent suspect is the surge damper or pressure switch. Adjustments to the aligning screw might not always alleviate the issue.
- If you’re unsure whether the pump is functioning or not drawing water, a diagnostic step could involve the use of a multimeter to trace the supply voltage, starting at the inlet housing.
- Tarnished brass contacts on the inlet could hinder the pump’s operation, so they should be inspected and cleaned as necessary.
- Loose Connections:
- Some users have traced the problem back to a loose connection within the pump itself. By wiggling the connection slightly, the pump operation could be restored, albeit intermittently.
- If a loose or broken wire is found in the submersible portion of the pump, a full replacement might be the only viable solution. While some may consider opening the sealed pump unit to fix the issue, it’s essential to note that these units are often designed to remain sealed, making self-repairs a challenge.
- Contact Pins in the Plug Connector:
- An often-overlooked culprit is the contact pins in the plug connector. Over time, and with regular use, these pins might need prying open a bit for optimal functionality.
- Cleaning these pins with a dash of WD40 in both the plug and socket could resolve the issue. Sanding connectors to eliminate corrosion and ensuring a snug fit can further enhance the connection.
- Maintenance Tips:
- Regular maintenance can preempt many of these problems. For instance, ‘Brasso’ with cotton wool buds can be effective in removing surface corrosion from female contacts. Following up with WD40 can ensure pins remain clean, as it’s safe for electrical components.
- For issues related to the surge damper, adjusting the small screw on the front might help. Turning it clockwise ensures the pump doesn’t stop when the tap is on, and turning it anti-clockwise ensures it switches off shortly after closing the tap.
Conclusion
Understanding your caravan’s water pump system and regularly maintaining it can save you a lot of hassle on your travels. Being proactive, from cleaning contacts to checking for loose connections, can ensure a smoother and more enjoyable caravan experience. When in doubt, always consult with a professional or the manufacturer to get the best advice for your specific situation. Safe travels!
