Some years ago I replaced my 20-year-old American-made washer with a New Zealand-made Fisher and Paykel. It came with all sorts of innovative features such as variable speed DC motors, a smaller agitator, automatic water level control, and other electronic whiz-bang features.
It ran great for a while until one day it refused to drain a full tub of grungy water. A call to their overseas service number prompted them to tell me to free up the drain pump rotor. This required removing the wet laundry and the standing water, then tipping the machine up on edge and removing the bottom cover.
There, a fractional horsepower motor was seen beside the main tub motor. It was about the size of a can-opener motor. A few spins by hand and the motor ran free. Problem solved.
Again, about a year later same drill. This time I pressured the company’s service tech for more information, like what was causing the motor to seize. “Soap buildup” was their answer. Once a year, they recommended I run a full tub of hot water with some dishwasher powdered detergent in the machine. Turns out that the phosphate in that soap is capable of cutting the sticky buildup better than the phosphate-free soap in laundry detergent.
About this time a friend told me that his F-P was in the same state, filled with wet clothes and stalled. I told him the fix, which he applied to solve it. Now I remember to do this trick about every year, and have only been caught a couple of times since, once when I ran an extra dirty load of muddy clothes. I have also learned to be extra careful with laundry, pre-cleaning muddy clothes with a hose. Wouldn’t you think they would have designed that little drain pump with a stronger motor to overcome the drag of soapy scum and extra silty drain water?
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
