  • Do it yourself washer repair 
  • How to fix a machine that will not spin or drain  –  I had problem with the lid switch lever.  Once tweaked it would again actuate and I could modulate the water input on / off to prove it was working
  • The belt was bad.  Replacement part number: Gates 6743  3L430K   Original Part Number:  33-6104D
  • How to fix a washer that will not stop filling with water – I had a problem with the fill switch "bong" that hung under the agitator case to shut the water off when it reached the fill point.  I removed it and cleaned it with CLR to remove some of the crust.  After this the washing machine started to function normally.

Dimatix Materials Cartridge The Dimatix Materials Cartridge is a snap-in replaceable printhead used with both DMP models and is available in 1 pL and 10 pL drop volumes. Based on FUJIFILM Dimatix' proprietary silicon MEMS technology, the 16-jet Dimatix Materials Cartridge is designed for high-resolution, non-contact jetting of functional fluids in a broad range of applications. The industry-first 1 pL cartridge can deposit features as small as 20 μm (20 millionths of a meter) to fabricate products such as organic thin-film transistors (TFTs) and printed circuits.
