Common Bosch Dishwasher SHX5AVF5UC/22 Problems and Their Causes
1. Bosch Dishwasher Will Not Turn On
Symptoms: The dishwasher does not respond when you press the start button. The display is blank or flickering, and no sounds are heard during operation.
Possible causes:
-
Power supply: A faulty outlet, damaged power cord, or tripped circuit breaker can prevent the dishwasher from turning on.
-
Door latch or switch: The dishwasher will not start unless the door is securely latched. If the latch or switch fails, the machine will stay off.
-
Control board: If power is present and the latch is working but the dishwasher still will not start, the control board may be defective.
Steps to fix:
-
Check the power supply. Make sure the dishwasher is plugged into a working outlet. Test the outlet with another appliance and inspect the dishwasher power cord for visible damage.
-
Check the circuit breaker. Reset the dishwasher breaker by switching it fully off and then back on.
-
Inspect the door latch and switch. Test the switch with a multimeter if needed. Replace it if it is faulty.
-
Test the control board if power and latch checks pass but the dishwasher still will not start.
When to call a professional: If the control board or internal electrical components are faulty, professional repair is recommended because replacement requires specialized electrical diagnosis.
2. Bosch SHX5AVF5UC/22 Not Draining
Symptoms: Standing water remains at the bottom of the dishwasher after the cycle ends, or the water drains very slowly.
Possible causes:
-
Clogged drain filter: Food particles, grease, and soap scum can build up and block water flow.
-
Clogged drain hose: A kinked or obstructed hose can stop water from leaving the dishwasher properly.
-
Faulty drain pump: If the drain pump is not moving water out, drainage will fail.
Steps to fix:
-
Clean the drain filter located at the bottom of the dishwasher under the spray arm.
-
Inspect the drain hose for kinks, blockages, or debris. Remove and clean it if needed.
-
Test the drain pump with a multimeter for continuity. Replace it if faulty.
When to call a professional: If the drain pump is bad or drainage problems continue after cleaning the filter and hose, professional replacement is the safer choice.
3. Bosch SHX5AVF5UC/22 Leaking
Symptoms: Water leaks from the sides, bottom, or front of the dishwasher during or after a wash cycle.
Possible causes:
-
Damaged door seal: A cracked or worn door seal allows water to escape.
-
Clogged drain hose: Water may back up and leak if the hose is blocked or misrouted.
-
Faulty pump assembly: A cracked pump housing can leak during operation.
Steps to fix:
-
Inspect the door seal for cracks or tears and replace it if damaged.
-
Check the drain hose for kinks, cracks, or poor positioning.
-
Inspect the pump assembly for cracks or holes if the leak appears to come from underneath.
When to call a professional: If the pump assembly is damaged or the leak continues after replacing the door seal, professional service is recommended.
4. Bosch Dishwasher Cleaning Issues
Symptoms: Dishes come out dirty, with food residue or soap left behind after a wash cycle.
Possible causes:
-
Clogged spray arms: Blocked spray holes reduce water coverage.
-
Low water temperature: Water that is not hot enough will not clean effectively.
-
Malfunctioning circulation pump: A weak or failed pump reduces wash pressure.
Steps to fix:
-
Remove and clean the spray arms. Flush the holes with warm water and clear buildup with a small brush if needed.
-
Check that incoming water is hot enough. The dishwasher should receive water around 120 degrees Fahrenheit for best results.
-
Test the circulation pump with a multimeter if cleaning the spray arms and checking water temperature do not solve the issue.
When to call a professional: If the circulation pump is faulty or the heater system is not performing correctly, professional repair is usually necessary.
5. Dishwasher Making Strange Noises
Symptoms: Grinding, buzzing, or rattling noises during operation.
Possible causes:
-
Foreign objects in the spray arms: Broken glass or food debris may be caught inside.
-
Worn-out motor: A failing motor can create grinding sounds.
-
Damaged wash impeller: A cracked or loose impeller can cause noise and poor water circulation.
Steps to fix:
-
Remove the spray arms and inspect them for debris. Clean thoroughly and remove anything lodged inside.
-
If the noise continues, inspect the motor for signs of wear.
-
Inspect the wash impeller for cracks or damage and replace it if necessary.
When to call a professional: If the motor or impeller needs replacement, professional installation is recommended because these parts are more complex to access and replace correctly.

When to Repair vs. Replace Your Bosch Dishwasher
