Dishwasher Not Draining in Mersin – Diagnosis & Repair Same-Day
Quick Answer
A dishwasher that leaves water in the bottom at the end of a cycle is almost always caused by a blocked filter, clogged drain hose, faulty drain pump, or a stuck non-return valve. Usta Hemen diagnoses and fixes dishwasher draining problems across Mersin same-day from ₺250. Call (0 551) 711 93 55.
Introduction
You open your dishwasher at the end of a cycle to find 2–3 centimetres of dirty water sitting in the bottom. The cycle has finished, the dishes are (mostly) clean, but the water has not drained. This is one of the most common dishwasher complaints we receive from Mersin residents, and the good news is that in 80% of cases, it is a straightforward repair that takes 30–60 minutes.
Usta Hemen's appliance technicians serve all Mersin districts — Yenişehir, Mezitli, Toroslar, Akdeniz, Pozcu, and Viranşehir. We carry common spare parts (drain pumps, filters, non-return valves) for the most popular brands in our vans.
Why Is There Water in the Bottom of My Dishwasher?
Cause 1: Blocked Drain Filter (Most Common)
The coarse filter and fine mesh filter at the bottom of the dishwasher trap food debris during the cycle. If not cleaned every 2–4 weeks, these filters block completely and water cannot pass through to the drain pump.
How to check: Remove the bottom rack, unscrew the cylindrical filter (turn counter-clockwise), and inspect for blocked mesh.
DIY fix: Clean the filter under running water with a soft brush. If blockage is severe or filter is damaged, replace it.
Our repair: ₺250 (inspection and filter cleaning or replacement).
Cause 2: Clogged Drain Hose
The drain hose runs from the drain pump to the under-sink waste connection. In Mersin kitchen installations, this hose is often poorly routed with low sections where food debris and grease accumulate over time.
Symptoms: Filter is clean, but water still does not drain. Sometimes a gurgling sound at the end of the cycle.
How to check: Disconnect the drain hose from the waste connection under the sink and check for blockage.
Our repair: Clear hose blockage or replace hose. ₺300–₺400 depending on accessibility.
Cause 3: Faulty Drain Pump
The drain pump (tahliye pompası) is an electric motor that pumps water out of the sump at the end of the cycle. Pump failures are caused by:
- Foreign objects (broken glass, coins, cherry stones) jamming the impeller
- Motor winding failure
- Pump capacitor failure
Symptoms: You can hear the pump attempting to run (humming or buzzing) but no water drains. Or the pump is completely silent when it should be running.
Diagnosis: Our technician tests the pump motor with a multimeter and checks the impeller for obstructions.
Our repair: Clear impeller obstruction: ₺300. Replace drain pump: ₺500–₺800 including pump.
Cause 4: Blocked Non-Return Valve (Check Valve)
The non-return valve prevents drained water from flowing back into the dishwasher. In Mersin's hard water conditions, calcium deposits can stick this valve in the closed position, preventing draining.
Our repair: Clean or replace the non-return valve: ₺250–₺400.
Cause 5: Blocked Kitchen Sink Drain
Sometimes the problem is not the dishwasher at all. If the kitchen sink drain is blocked, the dishwasher (which drains into the same waste pipe) cannot empty. Check whether your sink drains freely.
Our repair: Clear sink waste blockage: ₺250–₺400.
Cause 6: Control Board or Programming Fault
In rare cases, the drain cycle is not being triggered due to a control board fault or incorrect program selection. Some dishwasher models (Bosch, Siemens) run a partial drain only at the end of certain eco cycles.
Our repair: Programme diagnosis and reset: ₺200. Control board replacement: ₺800–₺1,500 depending on model.

Dishwasher Maintenance Tips for Mersin
Mersin's water supply is moderately hard, which means limescale build-up is a factor in dishwasher maintenance:
- Use dishwasher salt — Fill the salt reservoir regularly. This softens the water and prevents limescale inside the machine.
- Clean the filter — Every 2–4 weeks, remove and rinse the filter.
- Run a hot maintenance wash — Once a month, run an empty cycle at the highest temperature with dishwasher cleaner.
- Check the spray arms — Remove and rinse the upper and lower spray arms every few months. Blocked spray holes reduce wash quality.

FAQ
How long does a dishwasher drain pump replacement take?
Approximately 45–75 minutes. We pull out the dishwasher, access the pump from below or the front panel depending on the model, replace the pump, and refit the machine.
Can I use my dishwasher if there is standing water in it?
We recommend not running additional cycles until the fault is diagnosed. Running the dishwasher with a blocked drain can put extra stress on the pump motor and potentially cause a flood if the sump overflows.
My dishwasher is 8 years old. Is it worth repairing?
For most brands, if the cost of the repair is less than 50% of the replacement cost, a repair is economically justified — especially if the machine is otherwise in good condition. We will always advise you honestly before starting any work.
Can you come on weekends or evenings?
Yes. Usta Hemen operates 24/7. There is a small surcharge for work after 20:00 and on Sundays.
Do you offer a guarantee on the repair?
Yes. We provide a 3-month guarantee on parts and labour for all appliance repairs. If the same fault recurs within 3 months, we return and fix it at no charge.
