Washing machine problems come in three families, and each points at a different part of the machine. Shaking is almost always balance, levelling, or worn suspension. Leaking is a hose, a seal, or a pump — and where the water appears tells you which. Refusing to drain is usually a filter or hose you can clear yourself in ten minutes. Knowing which family you are in is most of the diagnosis, and it is the difference between a $10 fix and authorising a repair the machine did not need.
This is a deep-dive guide in Unitech’s appliance repair series. For deciding whether a repair is worth it, see repair or replace.
Key Takeaways
- A washer that shakes is usually not broken. Load balance, levelling feet, or shipping bolts left in after installation cause most violent spin cycles.
- Where the water appears identifies the leak. Back means hoses, front means the door boot, underneath during drain means the pump.
- The drain pump filter is designed to be cleaned by the owner. On front-loaders it sits behind a small panel at the base and traps coins, buttons and lint — the first thing to check on any no-drain fault.
- Replace rubber fill hoses with braided stainless every five years. A burst fill hose is one of the most damaging failures in a house, and it is entirely preventable.
- Washer repair labor runs $165–$265, with pumps and valves at the low end and bearing or transmission work at the top.
Family 1: The Machine Shakes or Walks
Unbalanced load
A single heavy item — a bath mat, a comforter, one pair of jeans — lands on one side of the drum and the spin cycle amplifies it. Redistribute the load and run the spin again. If that resolves it, the machine is fine.
The machine is not level
All four feet must sit firmly on the floor with the machine level front to back and side to side. A washer rocking on three feet will walk across a laundry room. Adjust the levelling feet and tighten their lock nuts. This is the single most under-appreciated cause of long-term washer wear — years of vibration loosens everything else in the machine.
Shipping bolts still installed
Front-loaders ship with transit bolts through the rear panel that lock the drum for transport. If they were never removed at installation, the machine vibrates hard from day one. Worth checking on any washer that has shaken since it arrived. Professional appliance installation exists partly to prevent exactly this.
Worn suspension rods or drum bearings
If the load is balanced, the machine is level, and it still shakes hard, the suspension is the likely cause — damper rods on a top-loader, or drum bearings on a front-loader. Bearing failure usually announces itself first as a rumbling or grinding that grows louder during spin. It is the most labor-intensive washer repair and the point where the repair-or-replace calculation starts to matter.
Family 2: The Machine Leaks
Trace the water to its source before assuming the worst.
- Water at the back — fill hoses or their rubber washers, or the inlet valve. Hose washers harden and fail with age; this is the most common leak and the cheapest to fix.
- Water at the front of a front-loader — the door boot seal. It traps grit and detergent residue, and tears at the lower edge where debris collects. Wiping it dry and leaving the door ajar between washes extends its life significantly.
- Water underneath, only during drain — drain pump housing or the pump hose.
- Water only during fill — inlet valve or its connections.
- Water underneath, all the time — the tub itself. On an older machine this is corrosion, and corrosion through a tub is structural rather than repairable.
The hose warning is worth taking seriously. A burst fill hose delivers water at mains pressure for as long as it takes someone to notice. Replace rubber hoses with braided stainless every five years, and close the supply valves if the house will be empty for an extended period.
Family 3: The Machine Will Not Drain or Spin
Blocked drain pump filter
Start here. On most front-loaders a small access panel at the base hides a screw-out filter that catches coins, buttons, hairpins and lint. It is meant to be cleaned periodically by the owner. Put a shallow tray and towels down first — there will be standing water.
Kinked, clogged, or badly positioned drain hose
The hose can kink behind the machine, clog with lint and detergent residue, or be pushed too far down the standpipe, which siphons water back out. A standpipe height outside the manufacturer’s specified range causes intermittent drain faults that look like a failing pump.
Failed drain pump
If the filter is clear and the hose is fine, the pump itself may have failed. A pump running with a grinding noise and no water movement usually has a blocked impeller; silence during the drain portion of the cycle points at the pump or its control.
Failed lid switch or door lock
Machines will not spin unless they believe the lid or door is securely closed. A failed lid switch on a top-loader or a door lock assembly on a front-loader stops the spin cycle entirely — so the drum fills, washes, and then sits full of water. Mechanical wear items, quick to replace.
Slow fill mistaken for a drain fault
Worth ruling out. Mineral scale on the inlet valve screens restricts the fill so the machine extends the cycle waiting for a water level it never reaches, then throws an error. It reads as a valve failure but is often just a blocked screen — see what hard water does to appliances.
What You Can Do Yourself
- Level the machine and tighten the lock nuts on the feet.
- Clean the drain pump filter every few months.
- Check and clear the drain hose for kinks and confirm the standpipe height.
- Inspect the fill hoses for bulges, cracks and hardened washers; replace with braided stainless every five years.
- Wipe the door boot dry and leave the door ajar between loads on a front-loader.
- Clear the inlet valve screens annually with the supply valves shut off.
- Stop overloading. Overloading is the leading cause of premature bearing and suspension wear.
Why Houston Washers Wear Faster
Hard water is the quiet factor. Mineral scale collects on inlet valve screens and in the water lines, restricting fill and reducing detergent effectiveness — which pushes people to use more detergent, leaving more residue in the door seal and dispenser. Homeowners across Richmond and the groundwater-served communities of Fort Bend County see this most sharply.
Garage and utility-room installations on unlevel slabs are the second factor. A machine that rocks slightly from day one accumulates suspension and bearing wear for years before anyone notices, which is common across Spring and Missouri City.

What Washer Repairs Cost
Unitech labor for washing machine repair runs $165–$265, flat-rate from the Original Blue Book for Major Appliance Job Rates, with parts quoted separately after diagnosis. Drain pumps, inlet valves, lid switches and door locks sit at the low end; bearing and transmission work sits at the top. Full rates by appliance are in the appliance repair cost guide.
Washers average 10 to 13 years of service life. Past seven years, a bearing or transmission quote deserves the two-test check in the appliance lifespan chart before you authorise it.

Get the Washer Diagnosed
Call (713) 333-0343 and describe the symptom precisely — “shakes on spin,” “leaks from the front,” and “fills but will not drain” point at three different components. Have the model number ready; it is usually inside the door or on the rear panel. Book online or see full rates on the pricing page.
