12 FAQs on the Thetford Water Pump 12v for Thetford Cassette Toilets

Hi - my Thetford C2 toilet is not flushing (no pump working) whilst trying to unscrew the glass fuse out from underneath to check it the threaded holder holding it in broke off - can I get a new piece for this ? also the fuse looked okay so what else should I check Thanks John

This part is no longer available. It is part of the Mechanism assembly which is our part 237147. This new assembly includes a blade fuse instead of the glass fuse.<br />The basic problem that you have is likely due to a faulty water pump, our ref. 229418. which will need replacing. The pump is found underneath the toilet roll holder which will lift out.

Our conway crusader flush has stopped working (C2L) also we are getting no hot water to the tap above. We have replaced the 3amp fuse in the cassette compartment but it has blown again. Help

You most likely have a faulty water pump in the toilet and this will need to be replaced. Our ref 129418. Sorry, unable to advise on your lack of hot water to tap. You will need to check the pipework.

My Cassette C200CWE will not start this year. I had to renew the 3amp fuse and power is getting to toilet.

Almost certainly a problem with the water pump inside the toilet. It may be that the rotor is stuck. If not you will need to replace it. Our ref 229418.

Hi, my thetford c200 toilet used to flush but the led didn't illuminate when nearly full. I purchased a new thetford led and still no joy, it actually overflowed. Now the fuse keeps blowing as soon as the flush is pressed. It fans been about 3 weeks and dried out but the fuse still boles straight away. Can you help?

You appear to have two problems here. A faulty water pump is the probable cause of the fuse 'blowing'. Replacement water pump, our ref. 129418. <br />The overflow problem is likely to be a faulty reed switch which is the item that senses the waste water level. this is our ref. 130062 but this may be the part that you have already purchased.

Hello , we have a 1993 lunar meteorite and need to replace the water pump in the thetford toilet. On the pump it says Reich 12 V We have looked at your web page but need help in deciding which one is the right one for us. Could you help , please ?.

You will need our ref. 129418

Hi"--Tom I have a c2 cassette toilet and the fuse has blown, could it be the switch at fault, or the pump? if it`s the switch can this be replaced without removing any other parts please advise , plus cost of items

Most likely to be the pump that is the problem. It may have suffered frost damage. our ref. 129418

How do I determine if the switch is bad or if the pump is bad on a c2 cassette toilet. I have already checked the 3 amp fuse and it was broken so I replace it. The toilet will not flush.

If the 3 amp fuse was broken then it it almost certain that the pump is faulty. The pump is beneath the toilet roll holder. You will need to undo a screw to remove the pump and then cut the electrical wire and remove the water hose. Strip back the wire and connect the pump directly across the battery to check operation.<br />If you purchase a new pump it comes complete with electrical connections and heat-shrink sleeving so that you can connect the new pump and fit the sleeving to seal from the water. Make sure you slide the sleeving onto the wire before making the electrical connection.

I have an Avondale Landrange 6400 1996 model fitted with an electric flushing Thetford cassette toilet. The electric flushing has stopped working. All the fuses are OK in the caravan. How do I strip it down to get to the motor to see if the motor is U/S? Is this a common fault? We put the caravan into storage with the flush working and first time out it wouldn't work. Any advice would be appreciated.

I believe you have a bench type toilet in your caravan and not the swivel bowl type. in this case the water pump is underneath the toilet roll holder to the right of the pan.<br />This holder will lift out to give you access to the water pump which should be held in by one screw. You will need to cut the wire leading to the pump to remove. The new pump comes with connectors and heat shrink sleeving.

Hi Tom,I have a thetford c402 c/x cassette toilet.When I press the flush button the fuse blows.

I think you will need to replace the water pump, our part 129418

Thetford porta potti. Not flushing. we have changed the fuse but still no joy. Any ideas please?

If you have a Thetford C2 bench type toilet then you will probably need to replace the water pump, our part 129418

how do I get to the switch so that I can replace the 12v pump on my c2 cassette?

The 12 volt toilet pump is underneath the toilet roll holder which will lift out. By removing a single screw the pump can be lifted out. The electrical wires have to be cut and the new pump installed using heat shrink sleeving to cover the electrical connection. I am not sure which switch you are referring to.

Toilet Electric Flush Will Not Work On a C200cwe

If you have checked the fuses it is likely that the electric pump has failed and will need to be replaced. Remove the blue operating button to access two screws. Remove the screws and lift the assembly ( held only by mastic ) to access the switch and pump. Before changing the pump make sure that you have continuity through the switch when depressed. If no continuity then the switch may be at fault. If you do have continuity then replace the pump. Replacement pump is our part 229418.<br />Switch part is 237090<br /><br /><div rel="qbp" style="margin-bottom:-20px;" class="well well-sm"><a id="aQuickViewCross_1" class="btn btn-xs btn-primary btn-quickview2" style="color:#fff;" title="Quick View" data-target="#product-details-modal" data-toggle="modal" data-id="29418">Quick View</a>   <img src="/product_images/BU518500_thumb.jpg" style="height: 40px;border: 1px solid #c0c0c0;" />  Thetford Bezel with push button 2377162 Thetford 200CWE</div><br />

Straightforward Replacement For Failed Pump.

by Mr JMP Hunter (26 May 2025)

(5/5)

Replacement pump arrived quickly and was a simple and straightforward job to fit. Cheaper than other sources. Particularly liked the crimp on connectors and the shrink on sleeve. For extra waterproofing I used a glue gun to coat the wires each end before shrinking the sleeve.

Flushed With Success

by Kev Fowles (20 Jun 2024)

(5/5)

We bought this Thetford water pump to replace the existing OEM Thetford pump that had finally stopped working after 12 years of use. There are plenty of alternative retro fit pumps out on the market but we decided that after 12 years trouble free flushing that we would go for the OEM Thetford replacement pump.
Ordered placed and pump kit arrived in two days, great service . It fitted and installed no problems other than I'm not as flexible as I once was to work in limited space so very glad it worked as it said on tin ! , couple of hours and toilet was back in full flushing action . As anyone who's fitted this pump to Thetford c402 toilet cassette will know its a job you want to fit and forget for a least another 12 years .

Great Product, Fast Service

by Mike Dowson (07 Jun 2024)

I worked out that my flush ump had failed and searched online for where to buy one. Leisure Shop Direct came up, they had the product in stock and shipped it very quickly. The instructions with the pump were clear and it was a relatively easy task to fit it and the new pump is working fine.

Quiet Running Pump.

by Mel (Ex Trog) (25 Mar 2023)

(5/5)

My pump packed in, so i thought, ordered replacement, quick delivery, fitted pump but cable a bit to short, made an extension up with heat shrink on the connectors, only to find out the only wire i did not check was corroded , so repaired that cable, but left the new pump in as it runs quieter than the original pump, at least i now have a spare one.

C400 Series Pump

by Len Stevens (18 May 2022)

(5/5)

Pump is well made and replaced same. Previous pump appears to have seized for reasons unknown.
Easy to replace once access is made, but if you have large hand, like me, access is tight to get the old pump out. Once out it’s a case of removing a fuse, cutting cables, re splicing same, testing and refitting.
Cable on new unit is a tad short and with crimped fittings which were cut off to get through rubber grommet, so why Thetford fit them I don’t know, better I would think to put into box with pump and let buyer crimp in place. Overall another good purchase from Leisureshopdirect…

Replacement For Seized Pump

by Thetford 12v pump for cassette toilet (19 Aug 2020)

(5/5)

Flush pump now working. The old one lasted 7 years. It is fiddly to install as the connection requires crimping in a confined space and protected with a rubber sleeve which requires a heat blower (the connection has to be inside the tank). Eventually worked once I realised the fuse had also blown when the pump failed.
