After 4 years and some 300 days of use one of our Jabsco electric toilets stopped working. I changed belts before on them a few times but this time the pump seized completely so I had to order a replacement for 450 Eur, ouch! I saved the old pump and later rebuilt it using new matching ceramic/carbid pump seal and 2 water-protected roller-bearing for under 25 Eur total.
What happened is pump seal got clogged up and seized on the pump macerator shaft and started rotating as a whole on a shaft (not on ceramic/carbid pair as it should be doing), slowly eating away rubber seal and eventually letting the water/waste come on top of the bearing that eventually got soaked up and seized. Not sure if there is an easy fix to this design but worth knowing you can rebuild it for a fraction of price of a replacement pump using standard parts. Bearings are type 608 2RS and pump seal is BT-AR type with dimensions shaft D=12, carbid part D=24, carbid part compressed L=8mm, ceramic part D=26mm. Hope this post saves you some money if your pump packs up.

We had two of these toilets onboard and the cost of repairing them is crazy and is required far too often. These toilets are complete rubbish. This winter we are looking at replacing them probably with Sanimarin 31 toilets. That will fix them once and for all- hopefully!

I hope it for you.
We have also these Lite flush toilets for more than 8 years no.
The main problem is when flusching sometimes water flush out of the toilet.
The other problems are: every 3 a 4 years we have to change the small belt inside, not so expensif, and every year complete dismantle and
cleaning the whole system with a strong acid.
I think all brands have this problem in the salty and hot MED waters.

Dear Konstantin, 
Thank you so much for this information! It was most useful! I've already taken the toilet apart, now waiting for the spare parts to replace them.
