Treadmill (powerfirst treadmill) shorting out power . overload switch shorting out power.? how can we fix this problem?

get a multi meter and check the whole circuit for short or damaged wire --fixya cannot tell you whats damaged or where the short is since unit needs to be physically examined

An 'overweight' situation, often stated in error. Try lubricating the belt. I found this;

What does E8 mean on a treadmill? Overload Condition

Answer: I had an E8 error on my Ancheer treadmill last year. It means an overload condition. At the time I was at least 60 pounds under the stated weight limit.

Consider requesting from a vendor: Example: http://www.fitnessdepotottawa.com/new_product_info/treadmills/powerfirst/980.html

You would need to contact the maker of the treadmill for this information.

dead short in the motor or system
you have 2 options
get in an electrician to find/ fix the short
junk it as too expensive to repair
you have no options in using it until it is fixed as the unit could become alive and electrocute a person

Your assumption is correct, if you have a household circuit breaker popping, you have a short or over current situation. If you have too many other things plugged into the same circuit you could be overloading that breaker. Depending on how your home is wired, you could have a few (older homes may have quite a few) outlets feed by a single breaker. If you have used the treadmill in that outlet (with the same items plugged into that circuit), the breaker it's self MIGHT be going bad (popping at too low of current).

For safety, inspect the power cord, for any damage, and be replaced if there is any.

If the power core is undamaged, I would try plugging the treadmill in another circuit. Choose an outlet that was not affected when the breaker popped. It you use an extension cord to get to another outlet, be sure it's rated for enough current. If it still pops the same breaker it's the same circuit, and you need to plug it in somewhere else (probably in another room). If a different breaker pops, then the short in in your treadmill. At this point you will need to know something about electricity to further isolate the short.

HI,
All the treadmills have a power switch with Auto reset. If there s any overload detected it will automatically reset to off position To prevent any further damages. Just check the power switch of the treadmill. If its it off position then turn it one and check the treadmill. If the switch again rest to off position then try to call for a tech to repair the treadmill.

see the diagrams attached and you must test for to isolate the short.
the short can be a) power cord short b) outlet wall faulty with ground test and repiar c) ground to chassis. d) filter short e) power switch short f) coil or transformer faulty. and step on until you elminate the short USE the DVOM or VOM. g)motor h)board main
Before to do something RUN THE software calibration for diagnose, troubleshooting, and fix it.
God bless you

A couple likely issues would be:
1. Is the starter key installed correctly?
2. Has the onboard circuit breaker tripped? The breaker reset is next to the on/off switch, which is on the lower front of the unit. Press the button once firmly. If this was the problem, the treadmill should work again immediately. If the onboard circuit breaker trips repeatedly, there may be a short circuit in the machine, in which case you may be at risk of shock if the unit is not repaired properly.
3. Has the circuit breaker or fuse for the particular outlet you are using tripped? Try plugging another electrical appliance into the outlet. Does it get power? If the circuit breaker or fuse has tripped, that particular circuit may be overloaded or faulty. Only an electrician could tell you for sure.

Please followup if you need further assistance.

" Turn the power switch off, wait 1 minute and turn the power switch on again. If treadmill recovers to normal operation, you may continue to use the treadmill.
The lower board software contains a protective current measurement, should the limit exceed, it will give the ’lift motor overload’ -error. Try calibrating the lift motor and if not successful. Unplug unit remove motor shroud locate the lift motor. The lift motor driven nut is never supposed to reach either of the ends of the lift motor screw. Should this happen, the nut is likely to get jammed. Check that the nut is not against the motor frame nor against the stopper in the end of the motor screw. In a case like this the lift motor needs to be removed and the nut released by hand.
