Please help me Polaris PB4-60

My husband passed away last June. He always maintained and repaired the pool. I can’t afford any problems but I’m having one. The hose on the front of the pump in picture has sprung a leak at the connector. It seems to be getting more and more power behind it too. Also when the sweep is on tons of bubbles come out at the connection spot and I don’t know if this is related I just know I need help it is the hose that goes up out of the top and is connecting to that white thing
