Why is my washing machine drain overflowing?
Think air behind water. The drain must be properly vented for it to withstand the rush of water from a washing machine pump. If the washer drains into a dry well, then the dry well is probably clogged with lint. The easiest way to fix this is to seal up the washing machine waste hose against the open PVC pipe.
The washer can leak if it is overloaded or out of balance. If you have a washer that features a spray rinse function, interfering with the cycle by manually advancing the timer can cause the washer to leak. The manual advance can often cause the spray rinse cycle to go on too long and overflow.
- The water pump or drain pump is the part on a washing machine that drains the water from the tub. If you have water leaking from the washer during a wash or drain cycle, check the area of the drain pump. Look for signs of a loose hose clamp or a leaking hose connected to the pump first.
- Lifespan in Years. The average lifespan of a washer, whether it is a top-loader or a front-loader, is about 14 years. This is determined by calculating seven loads of washing per week, or doing one load per day.
- Switch the dryer's control knob to off, and unplug the dryer from the electrical outlet. You can do this by turning off the small valve on the dryer line or the main valve that supplies gas to the whole house. Disconnect the dryer from the gas line by unscrewing the flex hose from the line only.
Water Inlet valve. The Water Inlet Valve on your washing machine is used to fill the tub with cold, warm or hot water for the wash and rinse cycles. To verify that the valve is at fault, unplug the washer when the symptom occurs. If the washer continues to fill, then the water inlet valve is defective.
- Some machines have a button you push to reset its motor. On a machine without a reset button, unplugging the washer and then plugging it back in often serves as the means to reset it. Dry your hands before touching the washer's buttons, power cord or circuit breaker.
- If the washer won't drain there might be a clogged pump or hose. It's common for small socks or other small clothing items to get into the water drain system and clog the hose leading to the pump or the pump itself. Remove the hoses from the pump in order to remove the article of clothing.
- The best way to clean your top loading washer is simple:
- Select the hot water setting.
- Select the “extra rinse” option if your washer has that choice.
- Add ¾ cup of white vinegar to the bleach dispenser or fill to its max level.
- Allow the cycle to run until it has completed.
The former requirement of 1 1/2-inch pipe is not enough to handle the fast drainage of modern washers. As with all plumbing fixtures and appliances, a washing machine drain pipe must also contain a P-trap. Position the trap between 6 and 18 inches above the floor, with a standpipe of 18 to 30 inches above that.
- It's probably because the water in the trap has completely evaporated, allowing sewer gases to come in to the home. Back to “S” traps – The reason “S” traps aren't allowed is because they have the potential to suck, or 'siphon', water out of the trap as the water flows down the drain.
- The standpipe extends into the building to supply fire fighting water to the interior of the structure via hose outlets, often located between each pair of floors in stairwells in high rise buildings. Dry standpipes are not filled with water until needed in fire fighting.
- In most homes, there is a P-trap installed under the sinks in the bathroom and kitchens. A P-trap is a plumbing fixture that has several purposes. It traps debris that has drained from the sink and prevents it from forming a clog deep within the plumbing system, and to stops sewer gases from passing into the home.
