Toilet Flush Pump Connectors

Recommended Posts

Hi All , I need to renew a leaking flush pump om my Pegasus 534 ,when trying to remove the old pump the small PCB connector strip situated on the top of the toilet under the push plate which the wires are connected into by being PUSHED fitted into the strip ,I cannot remove the wires i have tried to  release the wires by pressing on the top of the metal strip but no success , so if you know how to remove these wires please could you advise ASAP , I could cut the wires and use strip connectors but I prefer to put things back as original if possible,

Thank You.

from memory the wires are fitted to a plug which connects to the edge of the printed circuit board and the plug should just pull off

Hi bob , yes there are 6 wires going into the plug I want to remove the two wires from the defunct pump and put the 2 new pump wires into the plug but they will not come out of the push in connections I want to know the method on how to release the wires they have no screws holding them in place!

they are more than likely soldered and the plug moulded over them all, a new pump may have the plug attached

or possibly the plug housing splits so you can solder a joint

Often on pump replacement the wires are cut an the new one connected via crimp butt connectors (frequently supplied with the new pump).

 

Thetford's website has 'how to' videos and FAQs.  Probably worth a look.  You Tube has other videos which may cover your toilet model, too?  Precise model number of your toilet - label in access hatch - may aid others to give specific instructions?

 

Some push-in terminal can be released by inserting a small screwdriver, nail or similar alongside the existing wire to open the jaws; until the new wire is inserted?

Hi Rodders, in my wisdom when the old pump was leaking I tried to disconnect  the wires but as per this post was unsuccessful , so I cut the wires at the control panel leaving about 25mm tails , I took the old pump to the dealers to ensure the exact model and then discovered the new pump had a  much shorter flex and as you say with 2 crimped ends and to rub salt in the wound it tells you to cut the old pump wire just above the top casing  this then eleviates the need to go anywhere near the internal PCB connector , hindsights a wonderful thing.:wub: i tried your tip re the nail down the wire but no go, I will therefore have to use two small connectors under the control panel .

Thanks for your advice.

Having said all that, it's a ridiculous layout having connectors in such a damp environment. I've just had to pull all ours out and dry / clean them. There I was thinking a few weeks in France would be relaxing! (well the rest of it is).
