A laundry dryer (2) has a casing (3), a laundry storing compartment (18) arranged within the casing (3) for receiving laundry (19) to be dried by passing process air through the laundry storing compartment, a heat exchanger (10) for dehumidifying the process air after passing the laundry storing compartment (18), and a removable condensate reservoir (28) for storing condensed water formed at the heat exchanger (10). The reservoir (28) has a reservoir outlet for draining condensate liquid stored therein and a closing element for closing the reservoir outlet when the condensate reservoir is extracted from a reservoir compartment (30). The reservoir compartment (30) is associated to the casing (3) for receiving and housing the removable condensate reservoir (28), wherein the removable condensate reservoir (28) can be extracted from and inserted into the reservoir compartment (30). A supply line (32) for cleaning a component of the dryer and including a supply line inlet fluidly connected to the reservoir outlet (29) when the removable condensate reservoir (28) is inserted in the reservoir compartment (30), a supply line outlet for delivering condensed water to the component to be cleaned, and a pump (44) for conveying condensed water from the supply line inlet to the supply line outlet. A coupling arrangement associated to the reservoir outlet (29) and/or the supply line inlet and adapted to actuate the closing element. The coupling arrangement is adapted to maintain the closing element in an open state when the condensate reservoir (28) is inserted into the reservoir compartment (30), such that condensate liquid can freely flow from the reservoir outlet to the supply line (32); and wherein the a portion of the supply line (32) is located above a maximum condensate liquid level of the condensate reservoir (28).
