GWL11 Fisher & Paykel Washer Spin issue

Having a problem with 15 year old F&P GWL11 washer. First issue I've had. Trying to decide whether it is worth spending money on a washer this old. The symptoms are slow spinning in the spin stage, lack of complete water discharge and a slight electrical smell. I went in the diagnostic mode and got an binary error code of 00100101 (translates to 37) which suggests blocked pump issues. Tipped up the machine and removed the drain pump. It spins freely and didn't find any foreign item or major gunk interfering with it. Can't find any blockage in the drain hose either. Any other ideas other than replacing parts like the drain pump, motor control module. Opinion of how much is with investing in a machine this old?

Thanks
