Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Pump will not run | Closed tap, low battery condition, mains or pump isolator switch turned off, dirty or poor contact in plug and socket, faulty wiring connections, blown fuse, or temporary system lockup. | Work through this checklist: confirm a tap is open somewhere, check the battery, make sure the mains and pump isolator switches are both on, clean the plug and socket contacts, check the wiring, and check the fuse box - then try switching the pump off and on again with its isolation switch. If that doesn't fix it, contact an authorised service agent. | DIY Check / Tech Fallback |
N/A | Pump keeps switching on and off even though every tap and the shower are shut | Either an air/water leak somewhere in the taps and pipework, or grit trapped in the socket's non-return valve. | Check the taps and pipework for air or water leaks. To dislodge trapped grit, press a blunt object such as a ballpoint pen into the nipple of the socket to hold the non-return valve open. If the pump is still within its 1-year warranty, contact the retailer for a replacement, or otherwise arrange repair through an authorised workshop. | DIY Check / Tech Fallback |
N/A | Pump keeps running and doesn't stop after around 30 seconds | Loose or compromised connections in the pipework allowing air entry or pressure loss. | Check all connections in pipework. If the issue persists, have repairs carried out by a specialist or contact an authorised service agent. | DIY Check / Tech Fallback |
Frequently Asked Questions
Q: What does the Whale Superfil pump kit do?
If you have a Whale Easi-Slide socket with a 12V connection, the Superfil kit lets you pump water into your onboard tank from an external container such as an Aquaroll or jerry can - so running out of water doesn't mean packing up to drive to the nearest tap.
Q: Which is better - a submersible pump or a pressure pump?
It depends what you need. Whale's submersible pumps are simple, compact, quiet and inexpensive, and come in three flow rates: standard (10.3 litres/min), premium (13.2 litres/min) and high (15.8 litres/min). The Watermaster Onboard pressure pump (8 litres/min) is fitted inside the vehicle and gives a smooth, steady flow; it has its own built-in pressure switch, can run dry without damage, and is built to last.
Q: Is a submersible pump quieter than a pressure pump?
Yes. A submersible pump is a centrifugal design with an impeller as its only moving part, so it runs very quietly. A pressure pump is simple to fit and very dependable, but it's noisier.
Q: When would I need a pressure switch or a surge damper?
A Whale pressure switch is for vehicles fitted with a submersible pump: it senses the drop in water pressure when a tap is opened and turns the pump on. Because it works with any tap, you aren't restricted to taps with built-in microswitches.
