The unit's display indicated a specific "Fault".
Upon inspection, the indication was correct; Pump Motor failure.
Using this EXCELLENT site, I was not only able to order the correct part, but also to watch a very nice DIY video.
And, YES, trying to get the clamps back on the hoses DOES take more time than I wish to state.
If it wasn't for the intricacy of 1.) puttng the hose in place , 2.) keeping the clamp "OPEN" , and 3.) sliding the clamp OVER the hose, all while kneeling on the floor, and trying to keep a light on the whole process, it would've been a BREEZE.
