Common Washer Problems: Which Ones You Can Fix Yourself and Which Need a Pro

Common Washer Problems

Your washing machine breaks, and your first instinct is to Google the problem. That’s smart. Some washing machine issues are genuinely easy to fix yourself — no tools, no technical knowledge, five minutes of your time. Others look simple on the surface but are actually symptoms of a deeper fault that gets more expensive the longer you wait or the more you poke at it.

The challenge is knowing which is which before you make it worse.

This guide is honest about that line. For every common washer problem, we’ll tell you exactly what’s likely causing it, what you can reasonably attempt yourself, and when calling a professional repair technician is genuinely the better move — both for your wallet and your machine.

⚠️First: A Word on Safety

u003cstrongu003e Key safety remindersu003cbru003eu003c/strongu003eAlways unplug before repairu003cbru003eShut off gas supply if applicableu003cbru003eNever touch motor / control board / wiring without trainingu003cbru003eIf you’re not certain what you’re looking at, stop and call a technician.

Problem 1: Washer Won’t Start

u003cstrongu003eWhat you’ll see:u003c/strongu003e You press start, nothing happens. Or the display lights up but the cycle never begins.u003cbru003eu003cbru003eCheck these yourself first:u003cbru003e

Call a pro when:

The power supply is fine, the door latches correctly, no lock is active — and still nothing happens. This points to a failed control board, a wiring fault, or a motor start capacitor failure. These require diagnostic tools to pinpoint and proper electrical knowledge to repair safely.


DIY difficulty: Low (power and latch checks) to High (anything beyond that)


Risk of making it worse: Moderate to High if you proceed past the basics

Problem 2: Washer Not Draining

u003cstrongu003eWhat you’ll see:u003c/strongu003e The cycle finishes (or stops mid-cycle) with standing water in the drum. Clothes come out soaking wet.u003cbru003eu003cbru003eCheck these yourself first:u003cbru003e

Call a pro when:

The filter is clean, the hose is clear and correctly positioned, but the machine still won’t drain. The next likely cause is a failed drain pump. A pump that has seized, burned out, or has an electrical fault requires diagnosis with a multimeter and replacement of the pump assembly — a repair that’s well within a technician’s standard visit but involves disassembling the machine’s lower section in a way that’s genuinely difficult without experience.

DIY difficulty: Low (filter and hose) to High (pump replacement)

Risk of making it worse: Low for the filter check. Moderate for pump work.

Problem 3: Washer Not Spinning

u003cstrongu003eWhat you’ll see:u003c/strongu003e The drum doesn’t spin at all, or spins so weakly that clothes come out dripping.u003cbru003eu003cbru003eu003cstrongu003eCheck these yourself first:u003c/strongu003e

Call a pro when:

The load is balanced, the drum isn’t overloaded, and the lid switch seems intact — but the machine still won’t spin properly. The next likely causes are a worn or broken drive belt, a failed motor coupling, worn drum bearings, or a motor fault.

A broken drive belt is technically DIY-able on some machines, but accessing it requires significant disassembly that varies considerably by brand and model. If you get it wrong, you can damage the drum support or motor mount. Worn drum bearings — which produce a loud rumbling during spin — will eventually damage the drum shaft and rear bearing housing if left unaddressed, turning a $200 repair into a $500+ one.


DIY difficulty: Low (load adjustment) to Very High (belt, bearings, motor)

Risk of making it worse: High for anything beyond load adjustment

Problem 4: Washer Leaking Water

u003cstrongu003eWhat you’ll see:u003c/strongu003e Water on the floor during or after a cycle. Could be a small amount or a significant puddle.u003cbru003eu003cbru003eCheck these yourself first:

Call a pro when:

Hoses and connections are intact, the door seal isn’t visibly damaged, detergent is correct — but water still appears. Internal leaks from the tub seal, pump housing, or a cracked tub require disassembly to diagnose. A tub seal leak, in particular, will damage the drum bearing if left unaddressed — it’s one of those faults that compounds quickly. Internal leak diagnosis and repair requires removing the drum assembly on most machines. This is not a DIY project.


DIY difficulty: Low (hoses, detergent) to Very High (internal seals)

Risk of making it worse: Very High for internal work — water damage to motor and bearings if not addressed correctly

Problem 5: Washer Making Loud Noises

u003cstrongu003eWhat you’ll see:u003c/strongu003e Banging during spin, grinding or rumbling through the cycle, squealing on startup, or rattling that wasn’t there before.u003cbru003eu003cbru003eCheck these yourself first:u003cbru003e

Call a pro when:

A grinding or rumbling noise that persists through the full cycle — not just spin — points to worn drum bearings. This is one of the most important faults to address promptly. Worn drum bearings are a moderately expensive repair ($200–$350 typically), but a drum bearing failure that’s ignored for a season becomes a damaged drum shaft, a seized rear drum support, and sometimes a cracked tub — turning that $250 repair into a machine that’s uneconomical to fix.

Squealing at startup suggests a worn motor coupling or a belt issue. Intermittent clicking can indicate a damaged spider arm (the support structure behind the drum on front-loaders). All of these require professional diagnosis to differentiate accurately.


DIY difficulty: Low (leveling, load) to Very High (bearings, spider arm)

Risk of making it worse: Very High if bearing noise is ignored — it escalates quickly

Problem 6: Washer Not Filling with Water

u003cstrongu003eWhat you’ll see:u003c/strongu003e The cycle starts but the drum never fills, or fills much more slowly than normal.u003cbru003eu003cbru003eCheck these yourself first:

Call a pro when:

Both valves are open, screens are clean, water pressure is normal — but the washer still won’t fill adequately. The water inlet valve inside the machine (which controls water flow into the drum electronically) may have failed. Testing a water inlet valve requires a multimeter to check solenoid continuity. Replacement is straightforward for a technician — it’s a 20-minute job — but involves disassembly and electrical testing that’s not appropriate for most homeowners.


DIY difficulty: Low (valve and screen checks) to Moderate (inlet valve replacement)

Risk of making it worse: Low to Moderate

Problem 7: Washer Smells Bad

u003cstrongu003eWhat you’ll see (or smell):u003c/strongu003e Musty or mildew odor from the drum, from laundry washed in it, or from inside the machine.u003cbru003eu003cbru003eFix it yourself:u003cbru003eThis is one of the few washer problems that is almost always fully resolved with DIY maintenance — and doesn’t typically require professional repair.

For front-load washers (the most common source of odor problems):

In Denver specifically:

hard water mineral buildup in the drum and on the seal creates additional surface area for bacterial growth. Monthly cleaning cycles are not optional in hard water areas.

u003cstrongu003eFor top-load washers:u003c/strongu003e

When to involve a pro:

If odor persists after thorough cleaning and the machine is a front-loader, the issue may be mold inside the door seal that’s penetrated the rubber and requires seal replacement. If there’s a burnt electrical smell — rather than a musty smell — stop using the machine and call immediately. Electrical odors indicate an overheating component.

Problem 8: Washer Displaying Error Codes

u003cstrongu003eWhat you’ll see:u003c/strongu003e A letter-number combination on the display — E1, F5, LE, UE, and others depending on brand.u003cbru003eu003cbru003eCheck these yourself first:u003cbru003eLook up the error code in your owner’s manual or on the manufacturer’s website. Many error codes are informational — they’re telling you something specific, and often the fix is straightforward:

A reset — unplugging the machine for 5 minutes — clears many transient error codes caused by power fluctuations or sensor glitches.

Call a pro when:

The error code persists after a reset, and the basic checks don’t resolve it. Persistent error codes on modern washers point to component faults — motor failures, control board faults, pressure switch failures, or sensor malfunctions. These require brand-specific diagnostic tools and knowledge of the fault code architecture. Guessing at the component and replacing parts randomly is an expensive way to approach it.

The Honest Summary: DIY vs. Pro

One More Thing Worth Saying

u003cpu003eThe most expensive washing machine repairs are almost always repairs that were delayed.u003cbru003eDrum bearing noise that’s ignored for a season becomes a cracked tub. A slow drain that goes unaddressed strains the motor over hundreds of cycles. A door seal leak that’s tolerated eventually damages the drum bearing below it.u003cbru003eIf you’ve tried the DIY steps and the problem persists, the cost of a professional diagnosis is almost always recovered in prevented secondary damage — and in most cases, the repair itself is less expensive than you expect.u003c/pu003e
