I've got the plastic cover off, and can see the contacts and down between them, but can't see how the housing actually comes apart- and not sure if I really want to take it completely apart if I can avoid it. |

Go to an electrical or electronic supplier and obtain a relay cleaner tool.It is like a very tiny file type device.If the contacts aren't real dirty-a regular clean,paper filing card will work.It is just abrasive enough to remove dirt films from the contacts. |

If the contacts are in really bad shape they may not be repairable. You can attempt to sand/file them into shape and they may work for a while. I have had good luck using products from Caig labs (DeOxit and DeOxit Shield) for cleaning and protecting contacts but sprays won't bring back badly damaged/worn contacts. They can greatly extend the life of ones in good condition though.
If you do manage to re-work the contacts so that they function again, you may want to consider taking the load off them. By using an external relay to handle the current you can take the wear off the timer contacts. The timer would only need to handle the current energize the relay coil. This may be an option that could extend the life of your timer if a new one is impossible to find. |

Part number is 35-2750. I think I may have got it working (but who knows for how long) and will be trying a load with water and clothes tomorrow. I tried to take a decent picture of the beast, but my phone had other ideas...

If I have to clean up contacts that carry heavy current and high voltage (washer timer etc)
I use very fine wet and dry paper soaked in Servisol 10 switch cleaner, I think it is called De-oxit over there. I place between the contacts close them with my finger and mover the soaked wet and dry about between the contacts. If the contacts are heavily pitted then it is more difficult as you need to a get a very thin and fine model makers file in there. Gary |
