Woke up this morning and my water pump is not working.

[JackShaftoe]

As the title says, I woke up this morning and the water pump is just doing nothing. It was fine last night and has given me no issues in the past. There is power on the boat and water in the tank but when you open a tap nothing. No water, no sound. Have checked for loose wires or any other obvious reasons why it wouldn't be working. It was cold in the night but it's been cold before. Any suggestions?

Fuse blown?

[Tony Brooks]

Whack it with the heel of a slipper. It might be a stuck worn out brush in the motor or a reluctant pressure switch. Then check you have 12/24V at the pump connections.

Checked all the fuses and seem fine.

But do you have electricity at the pump?

 

My boat had the water pump switch hidden away in a cupboard and could have taken ages to find if someone had turned it off.

Have you got any type of multimeter, to confirm you have power to the pump?

How have you checked the fuses ? (Multimeter on Ohms ?)

Have you got voltage at the pump ?

 

Edit : Everyone asking the same question !

Gave it a go. Nothing. Has always been fine before.

Where is it located? @Onewheeler's suggestion may well be correct but you won't know until you establish if there is an electrical supply at the pump.

No I don't. Guess I will have to get one.

I have a switch under the sink and have tried it a few times but nothing happening.

Do you have a bulb, some wire and a soldering iron ?

[Tony Brooks]

Take care but take a light bulb out of a fitment, disconnect both wires from the pump (often a chock block) and touch them on the bulb contacts. Try not to use an LED bulb.

AND, make sure the pump power supply switch is 'ON'

"woke up this morning and my water pump is not working"   ...........................    you make it sound like cause and effect

Scratch that. I tried something else and there is power going into the pump

So, what was the "something" and what was the "something else" ?

[JackShaftoe]

I attached a cigarette lighter charger to the wires coming out of the switch into the pump and it worked fine

The power might be enough to operate a cigarette lighter charger, but it might not be enough to get the pump started. The pump may have seized. The pump may have seized. Or there may just be a current drop in the line.

ok. Any suggestions on what I can try next?

How old is the pump?...ish.

That MIGHT suggest the switch is faulty but it could just as easily be further back towards the batteries.

 

Are the fuses torpedo shaped euro fuses? If so clean the tips and bent the holders together a little. Then when convenient buy a decent fuse holder and change. Blade types are good.

[JackShaftoe]

Couldn't tell you exactly but less than 5. About 2 to 3 years at guess
