How to unclog drain hose on Kenmore washer?
To unclog the drain hose on Kenmore washer model 79641393510, we unplug the washer, drain any standing water through the drain pump access hose, then clear the pump filter and check the drain hose for kinks or blockages. Finish by reinstalling and securing the hose correctly per the 79641393510 owner's manual.
Step-by-step: clear the clog safely
- Unplug the washer.
- Open the drain pump filter access panel.
- Unclip the small drain hose, place it in a shallow pan or floor drain, then remove the plug and drain the water.
- Twist the pump filter counterclockwise, remove lint and debris, then reinstall the filter securely.
- Inspect the main drain hose path for kinks, pinches, or crushing; straighten the hose routing.
- Reinstall the drain hose and secure it so it cannot work loose during draining.
Drain hose installation checks (prevents repeat clogs and leaks)
Use these model-specific placement rules from the manual when you put everything back together:
| Check | What to do | Why it matters |
|---|---|---|
| Standpipe height | Keep the hose end 29 to 96 in. above the bottom of the washer | Prevents poor draining and overflow |
| Insert depth | Insert hose about 8 to 12 in. into the standpipe | Too deep can cause backflow and odor issues |
| Securement | Use the elbow bracket and a tie strap | Prevents the hose from popping out and flooding |
When a part is likely involved
If the washer still will not drain after cleaning the filter and confirming the hose is not kinked, the drain pump can be the next most common cause. For this model, the drain pump motor is drain pump motor (4681EA2001T) - washer part by lg electronics 4681EA2001T.
Why it matters
A restricted drain path makes the washer drain slowly or not at all, which can leave water in the drum, reduce spin performance, and strain the drain pump. Keeping the pump filter and drain hose clear helps prevent leaks and repeat drain problems.

How big is a Kenmore 400 Series washer?
For Kenmore model 79641393510 (a 796.4139* front-load washer), the cabinet size is 27 in. wide x 29 3/4 in. deep x 38 11/16 in. high. With the door open, depth is 52 in. For exact placement and clearance details, use the 79641393510 owner's manual.
Dimensions and space you need
These measurements help you plan a laundry closet, doorway clearance, and hookups.
- Washer dimensions (cabinet): 27 in. (W) x 29 3/4 in. (D) x 38 11/16 in. (H)
- Depth with door open: 52 in.
- Recommended side clearance: at least 1 in.
- Recommended rear clearance: at least 4 in.

Quick size table
| Measurement | Size |
|---|---|
| Width | 27 in. |
| Depth (door closed) | 29 3/4 in. |
| Height | 38 11/16 in. |
| Depth (door open) | 52 in. |
Why it matters
Correct sizing prevents installation headaches like a door that cannot fully open, kinked water lines, restricted airflow, and vibration from a washer that is squeezed too tightly into a niche.

Is it worth replacing the drain pump on a washing machine?
Yes, replacing the drain pump on a Kenmore washer like model 79641393510 is usually worth it when the washer is otherwise in good shape and the problem is truly a failed pump, not a clog or drain-hose setup issue. We recommend ruling out filter and hose problems first using the 79641393510 owner's manual.
Check the easy (and common) causes first
A “won’t drain” symptom is often caused by a restriction, not a bad motor. Before buying parts, we recommend:
- Clean the drain pump filter (lint, coins, buttons can block flow).
- Verify the drain hose is not kinked, pinched, crushed, or stretched.
- Confirm the standpipe height is within the required range (not lower than 29 inches and not higher than 96 inches above the bottom of the washer).
- Make sure the drain hose is secured and not shoved too far into the standpipe (typically 8 to 12 inches).
- Reduce oversudsing by using HE detergent only; excess suds can slow draining.
When replacement is the right call
Replace the pump when the washer consistently fails to drain after the filter and hose checks, or when you hear abnormal pump noise (grinding, loud buzzing) and water movement is weak.
Common repair paths for this model include:
| What you observe | Most likely issue | Typical fix |
|---|---|---|
| Slow or no drain, debris found | Clogged pump filter | Clean filter and retest |
| Hose routed wrong or too high | Drain installation issue | Correct hose height/routing |
| Hums but won’t move water | Pump impeller jammed or worn | Replace pump or pump motor |
| Intermittent draining | Partial blockage or failing pump | Clean first, then replace if needed |
If you’re replacing the pump motor on this model, the drain pump motor (4681EA2001T) - washer part by lg electronics 4681EA2001T is a common match for drain problems.
Cost and value guidelines we use
A drain pump repair is typically a good value when:
- The washer is under 10 years old.
- The tub and bearings are quiet (no roaring during spin).
- There are no recurring leaks from the door boot or hoses.
- The repair cost is well under half the cost of a comparable new washer.
Why it matters
A weak or failed drain pump can leave water in the drum, cause poor spin performance, and lead to repeat error conditions. Fixing the real root cause (clog, hose setup, or pump failure) restores normal draining and protects the washer from water-related damage.

How to tell if a washing machine drain pump is bad?
On Kenmore washer model 79641393510, a bad drain pump usually shows up as slow or no draining, standing water left in the drum, or abnormal grinding noises during the drain portion of the cycle. First rule out a clogged drain pump filter and a kinked drain hose using the steps in the 79641393510 owner's manual.
Quick checks before replacing parts
- Unplug the washer; if there is hot water inside, let it cool before servicing.
- Open the drain pump filter access panel and drain the tub using the small drain hose and plug.
- Remove and clean the pump filter (lint, coins, buttons, hair pins are common).
- Confirm the drain hose is not kinked or pinched and is routed correctly.
- Verify the standpipe height is not too high; maximum drain height is 96 inches above the bottom of the washer.
Symptoms that point to a failing drain pump
These signs are most consistent with a pump problem after you have cleared clogs:
- The washer hums during drain but water flow is weak or stops.
- Repeated “won’t drain” behavior even with a clean filter and clear hose.
- Loud grinding or rattling from the pump area (not the normal gentle humming/gurgling sound).
- Intermittent draining (works sometimes, fails other times).
- Water leaking from the pump area or pump housing.
What “normal” vs “not normal” sounds like
| What you hear | Most likely meaning | What to do |
|---|---|---|
| Soft humming or gurgling during drain | Normal pump operation | No action needed |
| Loud grinding, buzzing, or rattling | Debris in pump or worn pump | Clean filter; if it persists, replace pump |
| Hums but no water movement | Blockage or failed pump | Check filter/hose; then test/replace pump |
When a replacement is the right next step
If the filter is clean, the drain hose is clear, and the washer still drains slowly or not at all, replacing the pump is the practical fix. For this model, common pump-related parts include the drain pump motor (4681EA2001T) - washer part by lg electronics 4681EA2001T and the washer tub-to-pump hose 4738ER1002A (if the hose is restricted or collapsing).
Why it matters
A weak or failing drain pump can leave water in the drum, prevent proper spinning, and cause repeated cycle interruptions. Catching the issue early helps prevent water leaks and reduces strain on the washer’s drive and control system.
