5d / Sud
Maytag Washer 5d / Sud Error
The display is trying to say 'Sud' — excess suds. (On a seven-segment display, S-u-d renders as 5-d, which is why half the internet searches for the wrong code.) The washer has detected more foam than it can handle and switches into a suds-reduction routine: it stops, drains, adds water, and waits for the foam to collapse.

The short version: This is the one code where the machine is usually right and the laundry room is wrong. Too much detergent — or ordinary detergent in a high-efficiency machine — makes more suds than the pump can move. Fix the dose before you suspect the washer.
STEP 1 Likely causes, in order
Work down this list — it runs from the most common and cheapest to fix, to the least common and most involved.
- Too much detergentThe most common cause by a wide margin. Modern HE detergent is concentrated; the cap's 'full load' line is far more than most loads need. Two tablespoons is a realistic full-load dose for most machines.
- Non-HE detergent in an HE washerRegular detergent is formulated to make foam. An HE machine uses a fraction of the water, so the same dose produces foam the machine physically cannot drain.
- Fabric softener overdosedSoftener adds to the suds load and coats the outer tub, holding foam in the machine load after load.
- A slow drain making suds lingerFoam that should flush out in one drain instead hangs around if the pump filter or hose is partly blocked — the suds are the symptom, the drain is the cause. (Same family of fault as a drain error code.)
STEP 2 The safe checks
Power off and water off wherever a step says so. Nothing here opens the machine's cabinet, touches a gas line, or defeats a safety device.
- Let the suds routine finishDon't unplug the machine the moment 5d appears. The washer is actively fixing the problem — draining, diluting, and waiting out the foam. Interrupting it just restarts the wait.
- Run a rinse & spin with nothing in itOnce the cycle frees up, run rinse & spin empty, with no detergent at all. If the window still shows foam halfway through, run it again — you are washing detergent out of the machine itself.
- Run a hot cleaning cycleA washer-cleaning cycle (or the hottest empty wash the machine offers, with a cleaning tablet if you use them) strips the detergent film from the outer tub where suds hide.
- Cut the dose and check the bottleSwitch to HE detergent if yours isn't, and dose at roughly half what you've been using for a week. Most 'the washer is broken' suds cases are cured inside three loads.
- Check the drain pump filter if yours is accessibleIf suds keep returning on a correct dose, empty and clean the pump filter (towel and shallow pan ready — see the same checks as any drain fault). A filter full of lint mats holds foam in the tub.
Stop here and call a professional if…
- Suds appear even in an empty rinse with no detergent added, cycle after cycle. Detergent film alone doesn't survive that — look for a drain restriction or a pressure-sensor fault instead, which means a technician.
- The machine pairs 5d with standing water that won't drain at all. That's no longer a suds problem; it's a drain failure that happens to make foam.
- You see foam escaping from the door seal or detergent drawer during the cycle. Stop the load — that's an overfill/level problem, not a dosing problem.
