My MES30 works so well this summer I bought a MES40.
Thats why it is so strange to hear others having problems. I call in and they just amaze me helping. Seriously I don't rep MES, or even get kick backs, but their CSR as always been top notch. I was really surprized too, 'cause usually when you have as many setbacks as they had (I said that very nicely), the first thing to slip is the CSR.
I called last Thursday, the digital controller for my MES40 started acting like a slot machine...LOL. They agreed with my evaluation and I had a new controller arrive yesterday. That is pretty amazing to an old country boy that can't get Sears out for waranty repairs but every other Thursday. And usually its more like a month or 6 weeks. I have been trying to get those riding mowers to work since last July.
I am sorry for your woes. I am glad though I have not had any of the same problems. I am not usually that lucky.
