Hi, I have a bosch maxx 7 sensitive dryer which won't start. It gives 3 beeps and 3 lights 'drying', 'iron dry' and 'end' are on. I've cleand the bottom and door filter. Any ideas pls?
Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage.
CHECK THERMAL SHUT OFF THERMOSTAT USUALLY LOCATED ON THE BLOWER. for OHMS or resistance with a meter. Should show a closed circuit. Ohms WHEN THIS FUSE BLOWS IT WILL SHUT DOWN EVERYTHING.
NEXT Test the PUSH start switch with meter for OHMS. Should show OHMS when pushed in or on start, and no ohms or infinity when in off position.
If you hear a humming/clicking sound from motor area you more than likely have a bad motor. Try this test out to see if u have weak windings or relay/capacitor on motor. Open the dryer door and turn by hand the drum while machine is onONposition. And you or someone else presses the door engagement switch in. If it starts up then u have bad windings
Another thing to check is the belt safety switch. With a multi meter. Especially if u just replaced the belt.The belt safety switch is attached to theTensionerand motor. IT LOOKS LIKE A DOOR SWITCH SOMEWHAT a little black pc of plastic with 2 prongs going into it. Sits at bottom of motor. Under theTensioner. Attach meter clips to the 2 prongs on switch, Then when the little white push button is pressed in it should show continuity and none when released.
Lastly checkurDOOR SWITCH ?for continuity with a meter when the button is pushed in the (on/Door closed position,) it may have gone bad.
