Ctek D250S Error

In this archived thread I shared a video of an error sequence I was getting on my Ctek D250S



The thread ended with me suggesting all was fixed, but not so.

I ended up contacting Ctek and showing them the video. I was told it had failed and unfortunately it was outside the 2 year warranty period. They'd never seen that error sequence before. When I inquired about the potential for it to be assessed for repair, I was informed Ctek doesn't offer a repair service, but it was suggested that I inspect the 30A fuse inside the unit.

There are two 30A blade fuses inside. One had blown. Replaced fuse. All working normally again. I'm obviously grateful for the advice.
