I replaced the timer with a new one and the tub filled with water and then nothing except a hum and a ticking noise coming from the timer (more quiet and different than the original timer).
This sucks! The place I bought it from was the only one in town who had it in stock, so I payed the extra $20 to try to have it fixed for my wife tonight. Unfortunately, their return policy stated that the part must be unopened to return.
