models, the drain pump is only activated if the CCU detects a significant amount of water in the tub. Drain time will depend on water in tub.
† C01 – This test phase is performed only on STEAM models. NON-STEAM models skip this test.
‡ C06 – This test will run until a pre-set temperature level is reached. Water temperature will affect the duration of the test.
