Bosch compact washers in brief
Bosch washers sold here are compact front-loaders, 24 inches wide. They stack under a Bosch dryer or slide under a counter. You find them in condos, closets and second floor laundry rooms. Those spots make leaks a big deal, which is why Bosch builds in AquaStop.
AquaStop watches for water where it should not be. If the base pan gets wet, the washer stops and shows a code. Our Bosch appliance repair page covers the brand more widely.
E18 and a drum full of water
Bosch says E18 or F18 means the drain hose is blocked or kinked. In practice, the drain pump is the usual stop. A sock, a coin or a hair tie gets past the drum and jams the pump. The pump hums and the water stays.
Bosch also sets a limit on hose height. The drain hose should rise no more than 39 inches. Higher than that and the pump cannot push the water out. We clear the pump, check the hose run and test the pump motor. If the motor is worn, we swap the pump.
E23: water in the base
This is the leak code. Bosch tells owners to turn off the water tap and stop using the washer. We agree. The float switch in the base will not let it run until the pan is dry and the leak is found.
Leaks come from a few places. The door boot can tear at the bottom fold. The pump housing or its filter cap can seep. A hose clamp can loosen from years of spin. Too much soap can foam up and spill inside the cabinet. We tip the washer, dry the pan and trace the trail back to its source.
Door will not lock, or will not open
Codes E16 and F16 mean the door is not locked right. Shut it firmly until you hear a click. Check that no sleeve is caught in the seal. If it still fails, the door lock has worn out. It is a common part on Bosch washers and a quick swap.
A door that stays locked after the cycle often has water behind it. The washer will not release until the drum is empty. So this one can be a drain fault in disguise.
Banging, shaking and a loud roar on spin
E32 means the load is out of balance. One heavy towel with two shirts will do it. Bosch says to wash large and small items together. If the washer still thumps with a good load, a shock absorber has gone soft. The tub swings too far and hits the frame.
A roar that grows with speed is worse news. That is a drum bearing. Water got past the seal and the bearing rusted. It is a large job, since the tub has to come out.
Slow fill has its own code. E17 means low water flow. Bosch points to clogged screens in the inlet or the AquaStop hose, or low house pressure. Turn off the tap, unscrew the hose and brush the screen clean. Bosch warns that the AquaStop end holds an electric valve, so keep it out of water.
Your checklist before booking
- Write down the code and what the washer was doing.
- Look for a kink in the drain hose behind the machine.
- Cut the soap dose. Compact washers need very little.
- Clean the pump filter behind the small door at the front, with towels ready.
- Unplug it for thirty seconds to clear a stuck fault.
The cost of a Bosch washer repair visit
We keep it simple. The diagnostic at a home runs $79 or nothing at all if we do the repair. You get a set price, parts and labor both, ahead of any work. Pumps, locks and shocks are on our trucks most days. Our lines are open 6 AM until 9 PM daily and book same-day when we can. A licensed, insured, background checked tech does the job, and it carries a 30-day repair warranty.
On a Bosch, a pump, lock, boot or shock is worth fixing. With bearings on an old 300 Series, the math gets tight. We price it and say what we would do in your place.
A family has owned A+, and we are independent of Bosch. We repair Bosch washers in Washington D.C., where these compacts are common, and our D.C. repair page has details. Our techs work in Northern Virginia, Los Angeles, Houston and Chicago too. See washer repair for all brands and Bosch dryer repair for the unit on top. If yours is stacked, we unstack and restack the pair as part of the job.
