If you go to my site you will find information on the pump . The continious running problem is in fact quite common .
Also the number of electrical components in this units must number in the hundreds .
How or why it needs so may is any bodies guess.
I have only heard of one owner overcoming this problem and that was by fitteg two resistors but sorry i do not have the details of the to hand.
A search of the baby-benz.com forums search may bring it back to life.
The last I heard, his pump was still running
As far as repairs are concerned BBA reman (UK) will repair the pump for £140 less 15% if you mention my site when placing you order or simply click on the psp on that page.
