Speed Queen Washer Error Code Er, dr

The Er, dr code on a Speed Queen washer indicates that water remained in the tub at the end of a wash or rinse cycle when the machine expected the drum to be empty. This is a drain failure fault. The control board monitors water level through a pressure switch or sensor, and when water is still detected after the drain cycle has completed, it triggers this error to prevent the machine from proceeding to spin with a waterlogged load, which could cause mechanical damage or an overflow.

The drain system on a Speed Queen washer consists of several linked components: the drain hose, the drain pump, the pump filter or lint trap, and the household drain standpipe or utility sink connection. A blockage or restriction anywhere in this path can slow or stop water evacuation entirely. Common failure points include a kinked or improperly routed drain hose, a clogged pump filter packed with lint or debris, or a drain hose inserted too far into the standpipe, which can create a siphoning condition or an airtight seal that restricts flow.

In some cases the drain pump motor itself may have failed, either mechanically due to a foreign object obstruction or electrically due to a burned winding. The control board may also contribute if it is not sending proper power to the pump relay. The first diagnostic step is always to inspect the drain hose routing and the standpipe connection, then perform a hard reset by unplugging the machine for 15 seconds. If the code returns after the reset and the hose installation checks out, deeper component-level diagnosis of the pump and pressure switch is needed.
