Lead display is keep on flashing up on start sequence

Have you tried checking the fuse or the circuit breaker? Are both the washer and dryersharing the same two outlet duplex outlet or are they on two totally separate outlets? Just to eliminate/isolate the outlet question after you check the circuit breakers or fuses in your fuse box, try plugging the dryer into a separate outlet. If like many people you do not have an extra outlet in your laundry area, try plugging another item into the dryer outlet to check it for power. This is if you are talking about a gas dryer that works on a 120-volt electrical outlet. If it is an electric dryer it will be on a 230-240 volt outlet with a special plug. If you have an old circuit panel that is still using fuses as opposed to modern circuit breakers and if this Is an electric dryer, you would have a 240 volt disconnect plug more than likely inside the panel and if you firmly grab the handle and yank it straight out, you will see that the disconnect plug will have two short cigar shaped Buss Fuses in it. If this is the case one or more of those fuses could be blown. Depending on the electrical requirements of the dryer those two fuses amy need to be between 20-30Amp rated. or else if you have the manual take a look in it , perhaps one of the fuses is gone .
