2088-403-144 water pump/kwikee steps

I replaced my pump after taking the old one apart several times to get it to seal and to check and clean the rubber diaphragm. While I was waiting for the new one to arrive I decided to try one more time and sealed the seam with silicone adhesive and that stopped the leak and the 18 year old pump works fine. So I would try that first before ordering a new pump if it is leaking at the seam between the motor and pump housing. Your step problem problem sounds like a relay inside the control box that is failing(contacts arcing). After lubing the pivot points and that does not fix the problem I would go the the Kwikee web site and they give simple step by step procedure to isolate the problem to the motor, mag switch or control module. If you go though this procedure and report your findings here we can help you fix the problem.
