Dishes are not getting cleaned properly:

There are several reasons why dishes might not be getting cleaned properly in a dishwasher:

  1. Clogged spray arms: If the dishwasher's spray arms are clogged with debris or hard water deposits, they won't be able to spray water effectively. Remove the spray arms and clean them thoroughly or replace them if necessary.

  2. Dirty dishwasher: If the dishwasher is dirty or has food particles and grease stuck on the interior surfaces, it can prevent the dishwasher from cleaning properly. Clean the dishwasher by running an empty cycle with a dishwasher cleaner or vinegar.

  3. Improper loading: If dishes are loaded improperly, they can block the spray arms and prevent water from reaching all areas. Make sure to load dishes properly and not to overcrowd the dishwasher.

  4. Wrong detergent or insufficient amount of detergent: If you are not using the correct detergent or the right amount, your dishes might not get cleaned properly. Use a high-quality detergent specifically formulated for dishwashers, and follow the manufacturer's instructions for the recommended amount.

  5. Malfunctioning dishwasher components: If the dishwasher's pump, motor, or other components are not working correctly, the dishes won't be cleaned properly. In this case, you may need to call a professional to diagnose and repair the problem.

In summary, to fix a dishwasher that isn't cleaning dishes properly, try cleaning the dishwasher, checking the spray arms, loading the dishes properly, using the right detergent and amount, and making sure that all components are functioning properly. If none of these solutions work, it may be time to call a professional to diagnose and fix the problem.

Dishwasher is leaking:

There are several reasons why a dishwasher may be leaking:

  1. Door seal: The door seal is a rubber gasket that runs along the edge of the dishwasher door. If this seal is damaged or worn out, water can leak out. To fix this, replace the door seal.

  2. Water inlet valve: The water inlet valve is responsible for bringing water into the dishwasher. If the valve is damaged or malfunctioning, it can cause leaks. Replace the water inlet valve if it's not working properly.

  3. Spray arms: The spray arms distribute water throughout the dishwasher during the wash cycle. If the spray arms are clogged or damaged, they can cause leaks. Remove any debris from the spray arms or replace them if they are damaged.

  4. Drain hose: The drain hose carries water out of the dishwasher after the wash cycle is complete. If the drain hose is clogged or damaged, it can cause leaks. Clear any clogs from the drain hose or replace it if it's damaged.

  5. Float switch: The float switch is a mechanism that detects the water level in the dishwasher. If the float switch is stuck or damaged, it can cause leaks. Check the float switch and replace it if necessary.

If your dishwasher is leaking, the first step to fixing it is identifying where the leak is coming from. Once you've determined the source of the problem, you can take the necessary steps to repair or replace any damaged parts. However, if you don't feel confident in your ability to fix the issue on your own, it's recommended to hire a professional plumber or appliance repair technician to assist you.

Dishwasher won't start:

 If your dishwasher won't start, there are a few things you can check and try to fix it:
