Have you changed the drum unit? That's the only cause I've ever seen. If that didn't do it, then the engine PWB. =^..^=

You may be using the wrong drum unit. If memory servers me correctly the 4050/5050 takes a DK 716. The 3050 takes a ( DK 715) and it will fit but throw a code . This was a common mistake.

Good luck.
