Start/Pause and Options Buttons
The Start button initiates the selected wash program, while the Pause button temporarily halts the cycle – useful for adding forgotten items․ Options buttons allow customization of your wash․ These may include ‘Extra Rinse’, for thorough detergent removal; ‘Spin Speed’, to adjust the final spin intensity; and ‘Delay Start’, to schedule washing for a later time․
Refer to the control panel symbols in your Bosch Ascenta Washer manual (available as a PDF download) for a complete understanding of each option․ Proper use of these buttons ensures your laundry receives the precise care it needs, maximizing cleaning performance and fabric protection․

Maintenance and Cleaning
Regular cleaning extends your Bosch Ascenta Washer’s life! Clean the detergent dispenser, drum, seals, and filter per this manual for peak performance․
Cleaning the Detergent Dispenser
Maintaining a clean detergent dispenser is crucial for optimal Bosch Ascenta Washer performance․ Residue buildup can lead to clogs and reduced cleaning effectiveness․ To clean, remove the dispenser drawer – typically by pressing a release button or latch․
Rinse all compartments thoroughly under warm running water, using a soft brush to dislodge any lingering detergent or fabric softener․ Stubborn residue may require a soak in warm water with a mild cleaning agent․ Ensure all traces of cleaning solution are rinsed away before reinserting the drawer․
Regularly cleaning – ideally monthly – prevents issues and ensures your washer delivers consistently clean laundry․ A clean dispenser contributes to a longer lifespan for your appliance․
Cleaning the Drum and Seals
Regularly cleaning the Bosch Ascenta Washer drum and seals prevents mildew and odor buildup, ensuring fresh laundry․ Run a hot water cycle with a washer cleaner monthly, or utilize a cup of white vinegar․
After each wash, wipe down the rubber door seal with a dry cloth to remove excess moisture and detergent residue․ Inspect the seal for any signs of mold or debris, addressing promptly with a mild cleaning solution․
Pay close attention to the folds and crevices of the seal․ A clean drum and seal contribute to the longevity of your washer and maintain optimal hygiene․
Filter Cleaning Procedures
Maintaining a clean filter is crucial for your Bosch Ascenta Washer’s performance․ Locate the filter access door, typically at the front bottom of the machine․ Before opening, prepare for potential water spillage by placing towels nearby․
Carefully unscrew and remove the filter cap, slowly draining any remaining water․ Clean the filter thoroughly under running water, removing lint, hair, and small objects․ Inspect the filter housing for debris and clear it out․
Reinstall the filter cap securely, ensuring a watertight seal․ Regular filter cleaning prevents clogs and ensures efficient drainage, prolonging your washer’s lifespan․

Troubleshooting Common Issues
Encountering problems? This section provides solutions for issues like the washer not starting, water failing to drain, or the frustrating E18 error code․
Resolve these quickly for optimal performance!
Washer Not Starting
If your Bosch Ascenta washer fails to start, begin with the simplest checks․ Ensure the power cord is securely plugged into a functioning outlet, and verify the circuit breaker hasn’t tripped․ Confirm the door is firmly closed and latched; the washer won’t operate if the door isn’t properly secured․
Next, check the water supply valves – both hot and cold – to ensure they are fully open․ Insufficient water pressure can prevent the washer from initiating a cycle․ Also, examine the Start/Pause button; a brief press should initiate the cycle․ If these steps don’t resolve the issue, consult the error code section, as a specific code might indicate the problem․ A faulty door latch or control panel could also be the cause․
Water Not Draining
If your Bosch Ascenta washer retains water after a cycle, the drain hose is the first area to investigate․ Ensure the hose isn’t kinked, twisted, or clogged, and that it’s positioned at the correct height – typically between 24 and 39 inches․ Check the drain pump filter; it’s designed to catch lint and debris, and a blockage here is a common cause of drainage issues․
Locate the filter access panel (usually at the front, bottom of the washer) and carefully remove and clean the filter․ Inspect the drain pump itself for obstructions․ If the problem persists, an error code may appear, providing further diagnostic clues․ A failing drain pump could also be the culprit, requiring professional repair․
Error Code E18 – Detailed Explanation
Error code E18 on your Bosch Ascenta washer signals a communication issue between the drum’s motor and the electronic control unit․ Essentially, the motor isn’t responding as expected․ This often indicates a problem with the motor itself, the wiring connecting it, or the control module․ Attempting a reset by disconnecting the washer from power for a few minutes can sometimes resolve temporary glitches․
However, E18 frequently requires professional diagnosis and repair․ Do not attempt to disassemble the motor or control unit yourself․ Contacting a qualified technician is crucial to accurately identify the faulty component and ensure a safe and effective repair․ Ignoring this error can lead to further damage․

Safety Precautions
Always follow general safety guidelines and avoid damaging the washer․ Never install with mismatched appliances, and do not immerse the control unit in water!
