Abstract

The Parent Patent suggested the addn. of a rubber-diaphragm non-return valve in the discharge pipe which is kept closed by a water column until the pumping cycle begins. After longer waiting periods there is a risk of this column seeping away so that the purpose of the valve (not to waste washing agents) is not achieved. This can now be overcome by briefly turning on the suds pump to replenish the water column, before every program starts and before fresh water and washing agents reach the suds tank.
