Speed Queen Washer Error Code Decimal Point: Network Link Lost

What does Speed Queen Right-most decimal point lit mean?

On Quantum frontload and topload washers, the display normally shows only cycle or price information. When the control cannot hear the network it is connected to, it lights the decimal point at the right end of the display (shown as: Right-most decimal point lit). The check is simple: the washer expects to stay in contact with whatever sits on the other end of its network cable, such as an audit or remote-settings device in a laundromat, and when that contact drops it raises the light. It does not stop the wash. Customers can keep paying and washing, but sales reports and settings sent from the network may not reach this machine until the link returns. The manual says the light can clear by itself after roughly a minute and a half, which suggests the control keeps listening and recovers when the line comes back. If it does not clear, the manual's next step is to cycle the washer's power. A light that keeps returning points at the cable, a connector, the device at the other end, or the washer's own network input.

Affected models and control systems

Speed Queen Quantum frontload washers (FLW1535C family) and Quantum topload washers (TLW13C family) with the electronic control. Other controller generations show network trouble differently.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

Safe checks before calling for service

How a technician diagnoses Right-most decimal point lit

1. Confirm the display reading and whether the light is steady or comes and goes.
2. Check whether other machines on the same network are also reporting a lost link.
3. Inspect the network cable and connector ends for damage and seating.
4. Test the device at the far end for power and signal.
5. Test the washer's network port only after the cable and far device are cleared.
