问：挡风玻璃洗衣机泵不起作用。

When you operate your sprayers if you hear a quiet buzzing sound then the pump is still working. If there is no sound the pump is at fault. If a leak exists in your washer fluid system all the fluid will leak out before it reaches the sprayers causing the system not to perform its intended function. If a leak doesn’t exist and the buzzing sound from the pump can be heard than a restriction in the system is at fault. This can be corrected by using compressed air to clear the washer fluid lines or replacing the sprayer nozzles themselves. Having a technician检查您的洗衣机流体系统将是我第一个建议正确纠正您的问题。
