Clogged or Expired Filter
A filter past its life slows or stops flow to both dispenser and ice maker.
A water dispenser that gives no water, a weak stream, a constant drip, or warm water needs a diagnosis of the whole water chain, not a guess at one part. Potomac Refrigerator Pros takes dispenser calls by phone only, Monday to Sunday, 8:00 AM to 10:00 PM. Call (301) 368-8305 with the brand and model, the filter age, and whether the ice maker still works. A written estimate comes before work starts — no form, no email booking.

Name the exact symptom when you call, because a dispenser fault is not one fault: no water at all; a weak or slow stream; a drip that continues after you release the paddle; warm or room-temperature water; water that tastes off; or a dispenser that works while the ice maker fails, or the other way round. That last split matters: dispenser and ice maker share the supply in many models but take different paths after it, so one working and one failing narrows the fault. Potomac water matters here too: WSSC Potomac River supply averages 120–130 mg/L dissolved calcium and magnesium, classed as hard, so scale and sediment can slow a filter or a valve — a filter check comes before assuming the dispenser itself has failed.
No single symptom maps to one part. Diagnosis is inspection, with a multimeter and temperature readings, not a phone guess.
A filter past its life slows or stops flow to both dispenser and ice maker.
The valve that opens for water sticks, leaks, or never opens.
A frozen line in a cold spot, or a kinked line behind the unit, starves the dispenser.
A paddle or switch that does not signal the valve leaves the dispenser dead.
A board that never tells the valve to open, or opens it at the wrong time.
Weak household or supply pressure leaves the stream slow even when every part works.
Check the filter age and whether it is seated correctly, check that the water supply is on, and look for a kinked line behind the unit only if you can reach it without moving a built-in or pulling on connections. Check whether the ice maker still works and whether other taps in the home have normal pressure — if the whole home is slow, the fault may be plumbing, not the fridge. If water is leaking, shut the supply, mop and dry, and call. Never remove panels or touch the valve or wiring yourself.
Call: Call (301) 368-8305 with brand and model if known, filter age, whether the ice maker works, the exact symptom, and your area or ZIP code.
Diagnose on Site: Each link in the chain is tested — filter, inlet valve, supply line, dispenser switch, and control board — with a multimeter, so you pay for the failed part, not a guess.
Written Estimate Before Work: Plain-language diagnosis and estimate first, and you decide. A control-board fault, with the replacement comparison where relevant, comes before any work.
Repair and Test: The failed part is replaced, the line is flushed where needed, and flow, temperature, and shut-off are tested through several fills before the visit ends.
After: Filter-change timing for hard water, and what to watch — a returning drip, a slowing stream, or warm water. No fixed-for-life promise, and no warranty term — warranty terms are unconfirmed and must come from the partner.
No Potomac-specific repair price dataset exists, and none is invented here. Market figures, not a quote, and not a Potomac price. Your written estimate is the only price that counts.

No dispenser-specific part range from HomeAdvisor was in the research, so none is quoted here: the national totals are the honest frame, and your written estimate is the only price that counts.
If repair costs more than about half a comparable new unit, replacement is usually favoured; if far less, repair usually wins. Lifespans (Fridge.com analysis of DOE/AHAM data) are about 14 years for a top-freezer, 13 for a bottom-freezer, and 12 for side-by-side and French-door units, with built-ins about 15 years — guides, not promises.
Repair almost always.
Apply the 50% test: a filter, valve, or switch fault is an easy yes, while a control-board fault near half the replacement price is not.
Apply the 50% test; minor fixes such as a seal, filter, valve, or thermostat can be worth it at any age.
With a major failure, replacement is usually favoured; sealed-system repair on a standard unit over 10 years old rarely pays.
The exception: a repair buying two or three more years on a perfectly fitting unit can beat a swap needing joinery, and replacement add-ons can add several hundred dollars.

Straight answers for a water dispenser not working in Potomac, MD — diagnosis first, written estimate before work.
A dispenser that gives no water at all usually has a clogged filter, a failed inlet valve, a frozen or kinked supply line, a failed dispenser switch, or a control board fault. The filter and the supply are checked first, because they are the commonest and cheapest causes.
Detail: Check filter age and seating, and whether the ice maker still works — that split narrows the fault. A technician then tests valve, line, switch, and board in turn. Source: market research, dispenser symptom-to-cause table.
A slow or weak stream usually means restricted flow: a clogged or expired filter, low water pressure, a partly blocked valve, or a kinked supply line. In hard-water Potomac supply, a filter can load up faster, so filter age is one of the first facts to check.
Detail: Compare the stream with other taps in the home: if the whole home is slow, the fault may be plumbing, not the fridge. A technician tests filter, pressure, valve, and line. Source: market research, dispenser and hard-water sections.
A drip after release usually means the inlet valve is not shutting off cleanly, or air or pressure in the line keeps pushing water through after the paddle is released. A valve that sticks open slightly is the likeliest cause, and it should not be ignored, because a drip becomes a leak.
Detail: Note whether the drip is a few drops or a steady stream, and shut the water supply if it will not stop. A technician tests the valve and the switch, and checks the line for pressure problems. Source: market research, dispenser causes.
Warm dispenser water usually means the water is not spending long enough in the cold reservoir: heavy use, a warm kitchen, a reservoir fault, or a fridge section running warm. If the fridge section itself is also warm, the fault is cooling, not the dispenser, and it needs a different diagnosis.
Detail: Check the fridge temperature first — it should be at or below 40°F — and note whether the problem follows heavy use or is constant. A technician tests cooling, reservoir, and valve together. Source: market research, temperature and dispenser guidance.
Yes, a filter clogged with sediment or past its life can slow flow to a trickle or stop it entirely, and it can starve the ice maker at the same time. That is why filter age and seating are checked before any part is replaced, especially on hard-water Potomac supply.
Detail: WSSC Potomac River supply averages 120–130 mg/L dissolved calcium and magnesium, classed as hard. Replace the filter on the manual schedule, and sooner if flow slows. Source: WSSC, via the market research.
Replacing an overdue filter is a safe first step, and it often restores flow — but if the dispenser stays slow, drips, or stays dead after a new, correctly seated filter, call rather than replacing parts further. The remaining causes are a valve, line, switch, or board fault, which need diagnosis.
Detail: Keep the old filter and note its age for the call; those facts help the technician rule out supply before testing parts. Never run the fridge long-term with no filter unless the manual says the bypass is safe. Source: market research, safe resident checks.
