Of course, you can always use a Whale pump if you prefer, and the procedure for replacement will remain exactly the same. Tools you will need for repairing a Whale Watermaster pump: It is very bad form to criticize a company on a forum when the company does not have the opportunity to respond in a timely manner, and only one side of the communication is available. Another cause of failure is one of the pumps continuing to run after the external water container has been emptied. Spade connector after crimping tight with pliers.

I explained that normally on opening a tap the water flow would be good for a few seconds then slow then speed up again. To me this suggested the IC was controlling the voltage to the pump which was part of its surge prevention facility. The reply I received was no it doesn’t do that it’s your non return valve.In normal use, the water surrounding the pump in the container serves to keep it cool while operating. However, once the water container runs dry, if the situation hasn’t been noted and rectified, the pump can continue running, becoming progressively hotter until terminal failure occurs. My caravan documention suggests I have 3 years warranty on the Whale water system which is good but not if you have to continually keep returning the van to the dealer to get things sorted. Regarding the quote at the beginning of this, as you rightly point out the warranty and associated problems are the responsibility of the supplying dealer and it is to them that you should have taken this up with.

I don’t know what some of the parts cost to Whale but as an ex electronics iengineer I guess the IC a few pounds and a seals, non return valve kit etc similar money. It could be the pump but at this stage I am unwilling to spend on a new one to test. On some occasions I would open a tap and nothing until I had reset the system by switching off and on the pump supply at the control panel . Pull out the old pump after disconnecting the hose clip.

Push new cable through guide tube; mark where it emerges. Make sure the pump outlet is fully engaged with the hose. Push new cable through guide tube; mark where it emerges. Make sure the pump outlet is fully engaged with the hose On this you have my sympathy. When new with guarantee niggles it cost me much money and time in what seemed like continually returning my van. With the odd thing I got telephone help from a technician which was fine. For other things it was a frustrating experience. I should add, I know I am only talking about 1 dealer, but they have a ‘good’ name around here. I also feel that I read lots of similar reports on different forums.

Now the Achilles heel of the submersible pump is – they are submerged. They are designed so that the surrounding water is kept from the internal electrical components of the motor with watertight seals. However, the impeller shaft emerging via a seal, usually an ‘O’ ring, from the motor housing, can be prone to failure over time, resulting in the motor flooding and no longer functioning. One of the things that upset me most, was that there seemed to be zero realisation that, by not proBut viding a comprehensive service it absorbed my time, reduced my usage and enjoyment and was a cost. It was also inefficient for them and did not engender customer loyalty. Problems from the outset, the IC hadn’t been calibrated by the dealer or whoever so having been either near scalded or frozen in the shower I found the issue and re calibrated the pump/IC. I’ve a 2020 year Coachman VIP Caravan fitted with the Whale submersible high flow pump (in bowser Type) and the IC controller within the van. In the end as I was getting no where and more frustrated, I ended the call suggesting I would seek guidance from elsewhere.
