Safety First!

• Unplug your Bosch tumble dryer before starting work.
• Organize screws and parts meticulously to avoid confusion during reassembly.

Tools You'll Need:

• Screwdrivers (various sizes) or chargeable drill with correct extensions (if you have one).
• Vacuum cleaner.

Understanding Your Savings

Let's dive into some numbers. If your condenser tumble dryer runs approximately 2 to 2.5 hours per load to dry the clothes efficiently, it's drawing around nine amps or about two kilowatts. This means it's using around three to four kilowatts per load. However, if your dryer isn't efficient, it could be using an extra kilowatt because it takes longer to dry the clothes.

Now consider this: if you're saving one kilowatt per load and doing five loads a week, that's five kilowatts times 52 weeks in the year. This equates to a saving of 260 kilowatts per year. Given the current electricity prices, that translates to over 78 pounds per year in savings. These figures are conservative; the actual savings could be higher. And the best part? This job will only take you an hour.

Remember to use your full model number from the identification plate when obtaining parts for your tumble dryer from our website.

Diagnosing the Bosch Clothes Dryer Problem

If your dryer's drum is turning, but the container light comes on, you might have a problem with the condensing system, the pump system, or one of the sensors on the machine. Sometimes, a quick fix can rectify the problem: cleaning out the secret compartment inside the condenser plate. If that doesn't work, you'll have to remove the side panel of the machine to access the pump system.

Repairing the Bosch Tumble Dryer

You can begin by turning on the dryer and monitoring it for a few minutes to see if everything is working correctly with the heating system. If your machine runs for a few minutes and then cuts out, and the water container light comes on and the machine stops, you might have a problem with the pump system.

First, go down to the condenser plate and remove it. Clean this area thoroughly, then try running the machine again. If the problem persists, you'll need to remove the side panel and service the pump system.

Although our aim is to guide you through fixing the pump fault in this guide, we would recommend you watch the whole video to learn each step in detail.

Initial Cleaning and Inspection

1. Unplug the Machine: Always ensure the dryer is unplugged before starting any repair.

2. Remove the Condenser Plate:

• Clean the condenser thoroughly with a hose to remove any fluff and debris.
• Check the condenser chamber and clean any accumulated fluff.

3. Inspect the Sensor: The NTC sensor should have a clear ohms reading corresponding to air temperature and moisture levels.

Accessing the Pump System

1. Remove the Side Panel:

• Unscrew and remove the panel to access the pump system.

2. Inspect the Pump:

• Disconnect the return pipe and main pump pipe.
• Remove the pump cover by unclipping it and take out the pump.
• Clean any fluff from the sensor probes.
• Bench test the pump using a 230-240 volt power supply to ensure it operates correctly.

3. Clean the Pump Housing:

• Ensure the housing and surrounding areas are free of dirt and debris.
• Reassemble the pump and housing after cleaning.

Reassembling the Dryer

1. Reattach the Side Panel:

• Secure all screws in their original positions.
• Ensure plastic and metal screws are correctly placed to avoid damage.

2. Clean and Refit Internal Components:

• Thoroughly clean the internal ducting system and door filters.
• Reassemble all cleaned components, ensuring everything fits securely.

3. Test the Pump:

• Pour water into the system and check the pump's ability to move water to the collection tray.
• Ensure no leaks or blockages in the pipes.

Testing the Repaired Dryer

1. Load the Dryer: Place a load of laundry into the drum.
2. Run a Cycle: Observe the machine's operation for any error lights or issues.
3. Check the Water Container: Ensure it fills and empties correctly, indicating the pump is working efficiently.
