Question

I ran a load of clothes the other day and later checked on it to find it at the end of the cycle with water in the unit. I opened up the bottom panel to find the belt had broken. I replaced the belt last night and ran it through another cycle to find out that it does not drain the water during the spin cycle. It starts spinning fast with water in it and does not drain the water out the release hose.I took the hose completely out and made sure it was 100% clear by putting a wet/dry vacuum on it. I also hooked the vacuum up to the pump to make sure nothing was impeding its flow. I started another cycle and it still began to spin and not drain. I lowered the release hose and the water began to drain. Does this sound like the pump is going out or perhaps a switch is not triggering the pump to drain the water? How do I check this?Thanks!
