First timer here. The aquastop system cuts in multiple times during water intake. I've taken side panel off to reveal the water matrix etc. The float reservoir fills up and operates the cut-out switch. Noted that reservoir linked to the float chamber both have a brown gunge lining the chambers. Assume some fungal growth which may be restricting water flow and causing float to activate and stop water feed. I need to know how I can get into these chambers to clear this brown stuff or if/how I could run some cleaning liquid through the water intake. Machine is a 2005 model. If I knew how I would upload a pic but my skills very limited. Thanks for any assistance.
