Motor controller on Smartdrive 051 (phase 2) blows?

The fact that the pump now runs continuously suggests that the pump drive circuit was damaged when it blew. There is no way you will be able to repair it as it may have also corrupted the programme memory chip. Who installed it? That person should of thoroughly checked all parts of the machine for the reason that the 1st one blew before fitting the new one. If he was a qualified tech then the part should of come with a warranty so call him back. If not or if you fitted it yourself then you have wasted your money by not having the necessary knowledge to complete the job properly. Either buy another machine or get someone in who knows what to do & will guarantee his work.
