Direct answer
For the LG WM5500HVA front-load washer, load sensing, suds removal, heating, balancing and slow fill/drain can legitimately extend displayed time. First, note the exact stage where time stops decreasing.
What this covers
- LG WM5500HVA front-load washer (WM5500HVA)
- LG front-load washer; ThinQ-enabled controls and menu paths vary by model.
- The specific fault this record addresses: cycle takes too long or keeps adding time
What it does not cover
- ×The same symptom on a different LG product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The machine is adding rinses to clear excess suds
What separates it Time increases and foam is visible, often after a heavy detergent dose — see suds-foam.
How to confirm Correct the detergent type and dose; the extra rinses stop once foam does.
- 2
The machine is repeatedly redistributing an unbalanced load
What separates it Time stalls or increases specifically during the spin phase, with repeated slow tumbling and refilling — see not-spinning.
How to confirm Redistribute the load by hand; a bulky single item is the usual cause.
- 3
Load sensing revised the estimate upward
What separates it Time increases early in the cycle, once, and then counts down normally. The initial estimate is made before the machine has weighed and wetted the load.
How to confirm This is normal behavior, not a fault.
- 4
Filling is slow
What separates it Time increases during the fill phase specifically, and the machine takes a long time to reach level — see not-filling.
How to confirm Check supply faucets, hose kinks and inlet screens.
- 5
The machine is heating water internally
What separates it Long cycles on sanitize, allergen or tub-clean settings, which heat water well above the incoming supply temperature.
How to confirm Compare against a normal cycle. These cycles are legitimately much longer by design.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- The exact phase where time stops decreasing — fill, wash, rinse or spin. Each points at a different cause.
- Whether foam is visible through the door.
- Whether the load contained one bulky item.
- Which cycle was selected, since sanitize and tub-clean cycles are legitimately far longer.
Note the exact stage where the time stops decreasing
ReversibleThis is the single most useful piece of information for identifying the cause.
Run a small balanced load and observe fill, wash, drain and spin
ReversibleA controlled load separates load-related causes from machine ones.
Correct detergent dose if foam is present, or redistribute if spin is the stalling phase
ReversibleAddress the specific slow stage rather than resetting the machine.
Time the same controlled load again after correction
ReversibleConfirms the change rather than assuming it.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- WM5500HVA. LG front-load washer; ThinQ-enabled controls and menu paths vary by model.
- Type & capacity
- 4.5 cu. ft. FRONT-LOAD washer with a door boot/gasket — the same gasket-maintenance point as other LG front-loads for odour and mildew symptoms.
- Motor — Direct Drive inverter (no belt)
- Belt-less Direct Drive inverter motor, so noise/vibration is a drum-bearing and load-balance question, never a belt.
- Smart & wash features
- AI DD load sensing, TurboWash 360 fast wash, Steam and ThinQ Wi-Fi. Odd cycle timing is often AI DD adapting; connectivity faults are a ThinQ/2.4 GHz question.
- Symptom boundary
- This record covers LG WM5500HVA front-load washer when it cycle takes too long or keeps adding time. A different symptom on the same hardware, or this symptom on a different LG product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Stop for overheating, repeated electrical trips, smoke, or a machine that continues filling unattended.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. LG publishes this as "LG Frontload Washer - Wash Time Keeps Extending". Explains why the displayed time grows mid-cycle — the 'keeps adding time' half of the symptom. What that article does not carry is the model boundary — it is written for a product line, and WM5500HVA is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
The cycle time on my LG WM5500 keeps changing.+
That is AI DD (AI Direct Drive) doing its job: it weighs the load and detects fabric type at the start, then sets the wash motion and time to match — so the same cycle can show different times for different loads. It is a feature, not a fault. If the time seems stuck very long, an unbalanced or oversized load makes it add rebalancing time.
The time went up instead of down after I started the cycle.+
That is normal on most modern washers. The initial time is an estimate made before the machine has weighed and wetted the load; once it senses the actual load size and absorbency it revises the estimate. If it happens once early in the cycle and then counts down normally, nothing is wrong.
The cycle stalls at the spin stage and adds time repeatedly.+
That is the machine trying to redistribute an unbalanced load, usually a single bulky item. It will keep refilling and re-tumbling to try again. Redistribute the load by hand into an even ring and run Drain/Spin.
Does this answer apply to every LG model?+
No. It is scoped to WM5500HVA. LG front-load washer; ThinQ-enabled controls and menu paths vary by model.
What should I record before troubleshooting cycle too long or stuck time or adding time?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing cycle too long, stuck time, adding time. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for overheating, repeated electrical trips, smoke or continuous unattended filling.
