Common Washing Machine Hardware Failures
When my washing machine stops working properly, determining the cause of the problem can be tricky. However, there are some common hardware failures that I often encounter. Being able to identify and troubleshoot these issues can help me repair my washer and avoid the cost of a service call. Here are some of the most common hardware problems with washing machines and how I troubleshoot them.
Failing or Faulty Water Inlet Valves
The water inlet valves control the flow of hot and cold water into the washing machine. If one or both of these valves fail, it will cause a variety of problems such as:
- The washer not filling with water at all
- The hot or cold water not working
- The washer filling slowly or intermittently
To troubleshoot this, I first check that the water supply valves behind the washer are fully turned on. I also remove the fill hoses at the back and ensure I have good water flow through both hot and cold lines. If the water flow is weak, I may have a clogged inlet screen or hose that needs cleaning.
If the water flow is good but the valve still seems to be malfunctioning, I test the electrical connections and voltage at the valve. A bad solenoid or burned out valve can prevent it from opening properly. Replacing the inlet valve is the solution here.
Worn or Faulty Water Pump
The water pump pushes water through the washer during the fill, agitate, and drain cycles. If it starts to wear out, it may cause:
- Water not draining from the tub
- Weak or slow water flow
- Leaking water
- Burning smell from an overheated pump
To troubleshoot, I first check for obstructions in the pump and drain hoses that could impede water flow. Listening to the pump during the drain cycle can help determine if the pump is running properly.
If the pump is noisy, sluggish or not running at all, it likely needs to be replaced. I make sure to unplug the washer before testing electrical connections at the pump.
Worn or Seized Bearings
The main tub bearing allows the inner wash basket to spin smoothly. When it starts wearing out, I may hear loud noises when the tub spins. Other symptoms include:
- High-pitched squeaking or screeching
- Tub not spinning or spinning unevenly
- Rumbling, clanking or banging noises
Checking the tub by hand for smooth rotation can help diagnose a bad bearing. There are usually two bearings, one on the front and one on the back of the outer tub. Replacing the worn bearing is the solution here.
Broken or Worn Drive Belt
If the drive belt that turns the wash tub starts slipping or breaks, the tub won’t spin properly. Symptoms I watch for are:
- Washer not spinning or spinning unevenly
- Burning rubber smell from a slipping belt
- Loud squeaking noise during the spin cycle
To troubleshoot, I remove the rear panel to inspect the belt. Checking for cracks, damage or stretching indicates it needs replacement. I also make sure the pulleys are turning and the belt is seated properly on them.
When to Call a Repair Service
While many washing machine problems are DIY fixes, there are times when it makes sense to call a professional:
- If I need to disassemble and access internal components – this requires skills and special tools
- For electrical testing and diagnostics if I don’t own a voltmeter
- If the problem persists after I’ve tried several repairs
- For major repairs needed on newer, computerized washers
Knowing when to call for help prevents me from causing further damage or injury. For complex repairs, the expertise of an appliance technician is worthwhile.
Preparing for the Service Call
When I do need to call an appliance repair company, there are steps I take to prepare:
- I write down a detailed description of the washer’s symptoms and when they occur in the cycle
- I gather my model and serial number to provide accurate details
- I clear a path to access the washer for the technician
- I have a few potential times available in case an appointment is needed
- I ask ahead about service call fees so there are no surprises
Providing clear information to the technician helps them diagnose the problem and brings the right tools and parts. With some preparation, I can ensure the service call goes smoothly.
Preventing Hardware Failure
While washing machine repairs are sometimes unavoidable, I can take steps to help prevent problems:
- Cleaning the water inlet filters every 6 months prevents clogs
- Wiping gaskets and door seals keeps mold and mildew at bay
- Leveling the washer helps prevent leaks and noise
- Running monthly maintenance cycles with vinegar or bleach
- Avoiding overloading reduces strain on components
With proper care and maintenance, I can prolong the life of my washer’s hardware and avoid many costly repairs down the road. Taking preventative steps gives me peace of mind.
