What Does Error Code SUD Mean on a Maytag Washing Machine?

Excessive suds — too much detergent.

During wash and spin, the control board watches for signs of excess foam — typically motor load or drag on the drum and pressure-sensor readings that stay elevated because suds cushion the water. When foam prevents proper agitation, draining, or a stable spin, the board fires SUD (5D) and pauses to run an added suds-reduction rinse. Unlike a drain fault, the water leaves normally; the issue is foam volume, almost always from too much detergent or non-HE product in an HE machine.

Models affected: High-efficiency (HE) top-load and front-load Maytag washers, including models such as MVWC465HW, MVW7230HW, MHW6630HW, and MVW4505MW
What owners report: Owners commonly report SUD showing up mid-cycle or during the spin, often after switching detergents or overfilling the dispenser. It can be falsely triggered by regular (non-HE) detergent or by carryover buildup, and most find that cutting back to about a tablespoon of HE detergent and running an empty rinse clears it.

What Causes Error Code SUD?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Too much detergent 65% of cases
  2. 2
    Non-HE detergent 25% of cases
  3. 3
    Residue buildup 10% of cases

Wait — the washer runs a suds-reduction rinse and resumes on its own, usually within 30 minutes. To clear immediately, press Cancel, run a Rinse & Spin with no detergent, then restart the load.

When to Call a Professional

SUD is almost never a service issue. Call a pro only if the code appears on every load with correct HE detergent dosing — that points to a failing pressure sensor or a drain restriction trapping suds.

Average professional repair cost for this issue: $0–$0

Frequently Asked Questions

Can I keep using my Maytag Washing Machine when error SUD appears? +
Usually yes — SUD is a low-severity detergent notice that rarely stops the washing machine from working, but clearing the underlying cause prevents it from escalating.
What most commonly causes SUD on a Maytag Washing Machine? +
Across reported Maytag washing machine repairs, the most frequent is too much detergent (65% of cases), non-HE detergent (25%), then residue buildup (10%). Check them in that order before replacing any parts.
SUD keeps coming back after a reset — what should I check next? +
A reset only clears the stored SUD fault; if it returns, the detergent problem is still present. Move on to the physical checks — wait, then reduce detergent — since the code will reappear until the root cause is resolved. This is a beginner-friendly job needing only basic hand tools.
How much does it cost to fix Maytag Washing Machine error SUD? +
A DIY repair typically runs $0–$10 in parts, versus $0–$0 for a professional service call. Expect the work to take about 10–20 minutes.
Which Maytag Washing Machine models show error SUD? +
SUD is documented on High-efficiency (HE) top-load and front-load Maytag washers, including models such as MVWC465HW, MVW7230HW, MHW6630HW, and MVW4505MW. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
