Water usage depends on the cycle selected and the size of the load. We occasionally do a load of wash near the end of a short stay where we have electric only hookup, and by my calculations, we use about 12 to 15 gallons of water for a load. If conserving water, do not select pre-soak or extra rinse.
Newer Splendides do not have a lint filter, but there is a bottleneck in the vent system that can collect lint. Last year, our Splendide was not drying, so I removed and cleaned the entire flexible vent hose. Still no joy. Digging further, I found the rubber connector between the drum and the washer housing where the hose attaches was packed solid with lint. After I removed the rubber connector and cleaned it out, it was like having a new dryer.
