Speed Queen Washer Error Code Decimal Point Lit: Network Error
On Quantum frontload and topload washers, a lit decimal point at the far right of the display reports a network communication error. The control has lost contact with the network or external device it expects, and the wash cycle may still be able to run. Wait about a minute and a half, then power the washer off and on if it stays lit.
Medium: a communication warning; the washer may still run, but its network reporting is lost.

What does Speed Queen Right-most decimal point lit mean?
Quantum washers can be connected to a network or an external device for data. The control expects to talk to it regularly, and when it loses contact it lights the decimal point at the far right of the display. It is not a number or a word, just a small lamp, so it is easy to miss. The lamp reports communication rather than water, drum or door conditions, which is why the wash cycle may still be able to run while it is lit. The manual suggests giving it about a minute and a half to see whether it clears by itself, and lists the network cable and connector at the control, the network device or controller on the other end, and the power cycle behavior of the washer. A cable that was pulled when the machine was moved, or a network device that was switched off, is a common way to see it.

Quantum frontload (FLW1535C family) and Quantum topload (TLW13C family) washers, in the display's far-right decimal point.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- The right-most decimal point on the display stays lit
- The washer may still run its cycles
- The lamp returns after a restart if the network is still missing
Possible causes
Listed in Speed Queen's documentation
- Network cable and connector at the control
- Network device or controller on the other end

Other likely causes — what usually sits behind Right-most decimal point lit on this control. A technician confirms which one it is before any part is replaced.
- A network cable pulled loose when the washer was pushed back against the wall
- A network device or hub at the other end that lost power
Safe checks before calling for service
- Give it about a minute and a half to see whether the light clears by itself.
- If it stays lit, switch the washer off and then on again.
- Glance at the cable at the back for pulls or damage, leaving all panels closed.
- If the light keeps returning, schedule service by phone or online and tell us what else shares the network.
How a technician diagnoses Right-most decimal point lit
- Confirm the lit decimal point and ask what the washer is networked to.
- Check the network device and its power at the other end.
- Inspect the cable and connector at the control for damage or looseness.
- Power cycle the washer and watch whether contact returns.
- Test with a known-good cable.
- Replace the control interface only after the cable and the far end are proven.
- The network connector sits on the control board, behind a panel with live supply.
- The cause may be at the other end of the network, which needs the whole system looked at.
- Testing the interface means known-good cables and a meter.
How Right-most decimal point lit differs from similar codes
A lit right-most decimal point is a network lamp, not a numbered code. The EI codes are infra-red messages, and oFF is a security shutdown.
